**CHOOSING THE CORRECT PROCEDURE SW-846 is not intended to be an analytical trainin**  **g manual. Therefore, method procedures are written based on the assumption that**  **they will be performed by analysts who are formally trained in at least the basic principles o**  **f chemical analysis and in the use of the subject technology.**  **In addition, SW-846 methods, with the exception of required method use for the analysis**  **of method-defined parameters, are intended to be gu idance methods containing general**  **information on how to perform an analytical procedu re or technique which a laboratory can use**  **as a basic starting point for generating its own de tailed Standard Operating Procedure (SOP),**  **either for its own general use or for a specific pr oject application. The performance data**  **included in these methods are for guidance purposes only, and are not intended to be and must**  **not be used as absolute quality control (QC) accept ance criteria for the purposes of laboratory**  **accreditation.**

**2.0 INTRODUCTION The purpose of this chapter is to aid the analyst**  **in choosing the appropriate methods for sample analyses, based upon the sample matrix and t**  **he analytes to be determined. The ultimate responsibility for producing reliable anal**  **ytical results lies with the entity subject to the regulation. Therefore, members of the regulated co**  **mmunity are advised to refer to this chapter and to consult with knowledgeable laboratory person**  **nel when choosing the most appropriate suite of analytical methods. In addition, analysts**  **and data users are advised that, except where explicitly specified in a regulation, the use of SW**  **-846 methods is not mandatory in response to Federal testing requirements.**  **SW-846 analytical methods are written as quantitat ive analytical methods, and specific**  **methods may be used to demonstrate that a waste do es not contain analytes of concern that**  **cause it to be managed as a hazardous waste. SW-84 6 methods typically contain relatively**  **stringent recommended QC criteria appropriate to ma ny levels of analyses, including trace.**  **However, if a particular application does not requi re data of this quality, less stringent QC**  **criteria may and should be used. The choice of the appropriate sequence of analytic**  **al methods depends on the information sought and on the experience of the analyst. Appro**  **priate selection is confirmed by the usability of data (i.e., adequate for its intended use). The**  **use of the recommended procedures, whether they are approved or mandatory, does not release th**  **e analyst from demonstrating the correct execution of the method.**  **Sec. 2.1 provides guidance regarding the analytic al flexibility inherent to SW-846 methods**  **and the precedence of various QC criteria. Sec. 2. 2 reviews the information required to choose**  **the correct combination of methods for an analytica l procedure. Sec. 2.3 provides useful**  **information on implementing the method selection gu idance for organic analyses. Sec. 2.4**  **provides guidance on choosing procedures for charac teristic analyses. Sec. 2.5 provides**  **guidance on the determination of analytes in ground water. Finally, Sec. 2.6 provides** **SW-846 Update V TWO - 2 Revision 5 July 2014**  **information regarding choosing procedures for inorg anic analyte analyses. Tables and figures**  **referenced in this chapter are sequentially located after the last page of chapter text.** 
**2.1 GUIDANCE REGARDING FLEXIBILITY INHERENT TO SW-8 46 METHODS AND THE**  **PRECEDENCE OF SW-846 QUALITY CONTROL CRITERIA The specific products and instrument settings cite**  **d in SW-846 methods represent those products and settings used during method developmen**  **t or subsequently evaluated by the Agency for use in the method. Glassware, reagents,**  **supplies, equipment and settings other than those listed in this manual may be employed, p**  **rovided that method performance appropriate for the intended application has been d**  **ocumented. Such performance includes consideration of precision, accuracy (or bias), rec**  **overy, representativeness, comparability, and sensitivity (quantitation or reporting limits, now**  **referred to as lower limit of quantitation (LLOQ)) relative to the data quality objectives (DQOs) for**  **the intended use of the analytical results. In response to this inherent flexibility, if an altern**  **ative analytical procedure is employed, then EPA expects the laboratory to demonstrate and document**  **that the procedure is capable of providing appropriate performance for its intended applicatio**  **n. This demonstration must not be performed after the fact, but as part of the laboratory’s ini**  **tial demonstration of proficiency with the method. The documentation should be in writing, maintained**  **in the laboratory, and available for inspection upon request by authorized representativ**  **es of the appropriate regulatory authorities. The documentation should include the performance da**  **ta as well as a detailed description of the procedural steps as performed (i.e., a written stan**  **dard operating procedure). Given this allowance for flexibility, EPA wishes t**  **o emphasize that this manual also contains procedures for "method-defined parameters,**  **" where the analytical result is wholly dependent on the process used to make the measureme**  **nt. Examples include: the use of the toxicity characteristic leaching procedure (TCLP) t**  **o prepare a leachate, and the flash point, pH, paint filter liquids, and corrosivity tests. In th**  **ese instances, changes to the specific methods may change the end result and incorrectly identify**  **a waste as nonhazardous. Therefore, when the measurement of such method-defined parameters i**  **s required by regulation, those methods are not subject to the flexibility afforded in othe**  **r methods. Analysts and data users are advised that even for**  **those analytes that are not method defined, different procedures may produce some diff**  **erence in results. Common examples include the differences in recoveries of phenolic c**  **ompounds extracted from water by separatory funnel (Method 3510) and continuous liquid-liquid (**  **Method 3520) extraction techniques, differences in recoveries of many compounds between**  **Soxhlet (Method 3540) and ultrasonic (Method 3550) extraction techniques, and difference**  **s resulting from the choice of acid digestion of metals (Method 3050) or microwave digestion (Met**  **hod 3051). Where practical, the Agency has included guidance in the individual methods reg**  **arding known potential problems, and analysts are advised to review this information car**  **efully in choosing or modifying analytical procedures. Chapter One describes a variety of QC**  **procedures that may be used to evaluate the quality of the analytical results. Additional**  **QC procedures may be described in the individual methods. The results of these QC proced**  **ures should be used by the analyst to evaluate if the analytical procedures and/or any mo**  **difications are appropriate to generate data of the quality necessary to satisfy the data qualit**  **y needs of the intended application. The performance data included in the SW-846 method**  **s are not intended to be used as absolute QC acceptance criteria for method performa**  **nce. The data are intended to be guidance, by providing typical method performance i**  **n typical matrices, to assist the analyst in selection of the appropriate method for the intende**  **d application. In addition, it is the SW-846 Update V TWO - 3 Revision 5**  **July 2014 responsibility of the laboratory to establish actua**  **l operating parameters and in-house QC acceptance criteria, based on its own laboratory SO**  **Ps and in-house QC program, to demonstrate appropriate performance of the methods**  **used in that laboratory for the RCRA analytical applications for which they are intended** 

**. The regulated community is further advised that th**  **e methods here or from other sources need only be used for those specific analytes of co**  **ncern that are subject to regulation or other monitoring requirements. The fact that a method pr**  **ovides a long list of analytes does not mean that each of those analytes is subject to any or al**  **l regulations, or that all of those analytes must be analyzed each time the method is employed, or th**  **at all of the analytes can be analyzed using a single sample preparation procedure. It is**  **EPA’s intention that the target analyte list for any procedure includes those analytes necessary to**  **meet the DQOs of the project (i.e., those analytes subject to monitoring requirements and set**  **out in a RCRA permit or other applicable regulation, plus those analytes used in the methods**  **for QC purposes, such as surrogates, internal standards, system performance check compou**  **nds, etc.). Additional analytes, not included on the analyte list of a particular method**  **(s) but needed for a specific project, may be analyzed by that particular method(s), if appropria**  **te performance can be demonstrated for those analytes in the matrices of concern at the le**  **vels of concern. 2.1.1 Trace analysis vs. macroanalysis**  **Through the choice of sample size and concentratio n procedures, the methods presented**  **in SW-846 were designed to address the problem of " trace" analyses (<1000 ppm), and have**  **been developed for an optimized working range. The se methods are also applicable to "minor"**  **(1000 ppm - 10,000 ppm) and "major" (>10,000 ppm) a nalyses, as well, through use of**  **appropriate sample preparation techniques that resu lt in analyte concentrations within that**  **optimized range. Such sample preparation technique s include:**  **1. Adjustment of size of sample prepared for analy sis (for homogeneous samples)**  **2. Adjustment of injection volumes 3. Dilution or concentration of sample**  **4. Eelimination of concentration steps prescribed f or "trace" analyses**  **5. Direct injection (of samples to be analyzed for volatile constituents)**  **The performance data presented in each of these me thods were generated from "trace"**  **analyses, and may not be applicable to "minor" and "major" analyses. Generally, extraction**  **efficiency improves as concentration increases. CAUTION: Great care should be taken when performing**  **trace analyses after the analysis of**

**concentrated samples, given the possibility of cont amination.**  **2.1.2 Choice of apparatus and preparation of reage nts**  **Since many types and sizes of glassware and suppli es are commercially available, and**  **since it is possible to prepare reagents and standa rds in many different ways, the apparatus,**  **reagents, and volumes included in these methods may be replaced by any similar types as long**  **as this substitution does not affect the overall qu ality of the analyses.**  **2.1.3 Quality control criteria precedence SW-846 Update V TWO - 4 Revision 5**  **July 2014 Chapter One contains general QC guidance for analy**  **ses using SW-846 methods. QC guidance specific to a given analytical technique (**  **e.g., extraction, cleanup, sample introduction, or analysis) may be found in Methods 3500, 3600, 50**  **00, 7000, and 8000. Method-specific QC criteria may be found in Sec. 8.0 of most older ind**  **ividual methods, in Sec. 9.0 of newer methods, or in Sec. 11.0 of some air sampling metho**  **ds. When inconsistencies exist between the information in these locations, method-specific**  **QC criteria take precedence over both technique-specific criteria and those criteria give**  **n in Chapter One, and technique-specific QC criteria take precedence over the criteria in Chapt**  **er One.**
**2.2 INFORMATION NECESSARY FOR CHOOSING THE CORRECT PROCEDURE** 
**In order to choose the correct combination of meth ods to comprise the appropriate**  **analytical procedure, some basic information is nec essary. This includes information on:**  **1. The physical state of the sample 2. The analytes of interest**  **3. The analytical sensitivity needed 4. The analytical objective**  **5. Whether the purpose is quantitation or monitori ng**  **6. What sample containers and preservation will be used and what holding times may**  **apply 2.2.1 Physical state(s) of sample**  **The phase characteristics of the sample must be kn own. There are several general**  **categories of phases into which the sample may be c ategorized, including:**  **Aqueous Oil or other Organic Liquid Sludge Multiphase Sample**  **Solid Groundwater**  **Stack Sampling –Volatile Organics Sampling Train ( VOST) Condensate**  **TCLP or Extraction Procedure (EP) Extract There may be a substantial degree of overlap betwe**  **en the phases listed above and it may be useful to further divide these phases in certain**  **instances. A multiphase sample may be a combination of aqueous, organic liquid, sludge, and**  **/or solid phases, and generally must undergo a phase separation as the first step in the**  **analytical procedure. 2.2.2 Analytes of interest**  **Analytes may be divided into various classes, base d on the determinative methods used**  **to identify and quantify them. The most basic diff erentiation is between organic (e.g., carbon**  **containing) analytes and inorganic (e.g., metals an d anions) analytes.**  **Table 2-1 is an alphabetical list of analytes cite d within the SW-846 organic determinative**  **methods (excludes immunoassay and other screening m ethods). These analytes have been**  **evaluated by those methods. The methods may also b e applicable to other analytes that are**  **similar to those listed. Tables 2-2 through 2-38 l ist the analytes for each organic determinative**  **method. Table 2-39 indicates which methods are app licable to inorganic analytes.** **SW-846 Update V TWO - 5 Revision 5 July 2014**  **NOTE: Analysts should review the discussion in Sec. 2.1 of this chapter with regard to the** 

**presence of an analyte in a method versus the need for its analysis for a given project.**  **2.2.3 Sensitivity Some regulations may require a specific sensitivit**  **y or quantitation limit (LLOQ) for an analysis, as in the determination of analytes for t**  **he Toxicity Characteristic (TC). Drinking water quantitation limits, for those specific organic and**  **metallic analytes covered by the National Primary Drinking Water Regulations, are desired in**  **the analysis of groundwater. 2.2.4 Analytical objective**  **Knowledge of the analytical objective is essential in the choice of sample preparation**  **procedures and in the selection of a determinative method. This is especially true when the**  **sample has more than one phase. Knowledge of the a nalytical objective may not be possible or**  **desirable at all management levels, but that inform ation should be included in the project**  **planning document and transmitted to the analytical laboratory management to ensure that the**  **correct techniques are used during the analytical e ffort. Screening methods or composite**  **sampling may be highly beneficial for some applicat ions in order to generate a broader view of**  **contaminant distribution than may be possible with a more precise and more costly method.**  **Table 2-46 identifies some screening methods approp riate for different classes of organic**  **chemicals in certain matrices. 2.2.5 Quantitation or monitoring**  **The strategy for quantitation of compounds in envi ronmental or process samples may be**  **contrasted with the strategy for collecting monitor ing data. When there is little information**  **available about the composition of the sample sourc e (e.g., a well or process stream), mass**  **spectral identification of organic analytes leads t o fewer false positive results. Thus, the most**  **practical form of quantitation for organic analytes is often mass spectral identification. However,**  **where the sensitivity requirements exceed those tha t can be achieved using mass spectral**  **methods (e.g., gas chromatography/mass spectrometry (GC/MS) or high performance liquid**  **chromatography (HPLC)/MS), it may be necessary to e mploy a more sensitive quantitation**  **method (e.g., electron capture). In these instance s, the risk of false positive results may be**  **minimized by confirming the results through a secon d analysis with a dissimilar detector or**  **chromatographic column. Thus, the choice of techni que for organic analytes may be governed**  **by the sensitivity requirements and potential inter ferants.**  **Similarly, the choice of technique for metals may be governed by the sensitivity**  **requirements and potential interferants. In contrast, monitoring samples are analyzed to co**  **nfirm existing and ongoing conditions, tracking the presence or absence of known constitue**  **nts in an environmental or process matrix. In well-defined matrices and under stable analytica**  **l conditions, less compound-specific quantitation modes may be used, as the risk of fals**  **e positive results is less. 2.2.6 Sample preservation and holding times**  **Table 2-40 provides information regarding recommen ded sample preservation techniques,**  **sample holding times, and other information. Simil ar information may be found in Table 3-1 of**  **Chapter Three (inorganic analytes) and Table 4-1 of Chapter Four (organic analytes). Samples** **SW-846 Update V TWO - 6 Revision 5 July 2014**  **need to be extracted and analyzed within the recomm ended holding times for the results to be**  **considered reflective of native concentrations as c ollected. Analytical data generated outside of**  **the recommended holding times should typically be c onsidered as minimum values only. Such**  **data may be used to demonstrate that a waste is haz ardous where it shows the concentration of**  **a constituent to be above the regulatory threshold, but cannot be used to demonstrate that a**  **waste is not hazardous. However, regarding the inf ormation in Table 2-40, a longer holding**  **time may be appropriate if it can be demonstrated t hat reported concentrations are not**  **adversely affected from preservation, storage and a nalyses performed outside the**  **recommended holding times.**
**2.3 CHOOSING PROCEDURES FOR ORGANIC ANALYSES Table 2-1 summarizes the organic analysis options**  **available in SW-846. 2.3.1 Extraction and sample preparation procedures**  **for organic analytes SW-846 methods for preparing samples for organic a**  **nalytes are shown in Table 2-41. Method 3500 and associated methods should be consul**  **ted for further details on preparing the sample for analysis.**  **2.3.1.1 Aqueous samples Methods 3510, 3520, and 3535 may be used for extra**  **ction of the semivolatile organic compounds (SVOCs) from aqueous samples. Th**  **e choice of a preparative method depends on the sample. Method 3510, a separatory f**  **unnel liquid-liquid extraction technique, is appropriate for samples which will no**  **t form a persistent emulsion interface between the sample and the extraction solvent. The**  **formation of an emulsion that cannot be broken up by mechanical techniques will prevent**  **proper extraction of the sample. Method 3520, a continuous liquid-liquid extraction**  **technique, may be used for any aqueous sample and will minimize emulsion formation** 

**. Method 3535 is solid-phase extraction technique th**  **at has been tested for organochlorine pesticides, phthalate esters, polych**  **lorinated biphenyls (PCBs), organophosphorus pesticides, nitroaromatics and nit**  **ramines, and some explosive compounds, and may be applicable to other semivolat**  **ile and extractable compounds as well. The aqueous sample is passed through a solid**  **sorbent material which traps the analytes. They are then eluted from the solid-phas**  **e sorbent with a small volume of organic solvent. This technique may be used to min**  **imize the volumes of organic solvents that are employed, but may not be appropriate for a**  **queous samples with high suspended solids contents.**  **2.3.1.1.1 Acidic extraction of phenols and acid a nalytes**  **The solvent extract obtained by performing Method 3510, 3520, or 3535**  **at a pH less than or equal to 2 will contain the ph enols and acid/neutral extractable**  **organics of interest, and may contain some mildly b asic compounds. The**  **particular pH extraction conditions needs to be def ined during the project planning**  **process based on the desired target analytes and pe rformance goals.** 
**2.3.1.1.2 Basic or neutral extraction of semivol atile analytes** **SW-846 Update V TWO - 7 Revision 5 July 2014**  **The solvent extract obtained by performing Method 3510, 3520, or 3535**  **at a basic pH will contain the organic bases of int erest, if acid extraction is**  **performed first. It will also contain the neutral compounds of interest, if acid**  **extraction is not performed. Refer to Table 1 in t he extraction methods (3510**  **and/or 3520) for guidance on the requirements for p H adjustment prior to extraction**  **and analysis. 2.3.1.2 Solid samples**  **Soxhlet extraction (Methods 3540, 3541 and 3542), pressurized fluid extraction**  **(Method 3545), microwave extraction (Method 3546) a nd ultrasonic extraction (Method**  **3550) may be used with solid samples. Consolidated samples should be ground finely**  **enough to pass through a 1-mm sieve. In limited ap plications, waste dilution (Methods**  **3580 and 3585) may be used if the entire sample is soluble in the specified solvent.** 
**Methods 3540, 3541, 3542, 3545, 3546 and 3550 are neutral-pH extraction**  **techniques and therefore, depending on the analysis requirements, acid-base partition**  **cleanup (Method 3650) may be necessary. Method 365 0 will only be needed if**  **chromatographic interferences are severe enough to prevent quantitation of the analytes**  **of interest. This separation will be most importan t if a gas chromatography (GC) method is**  **chosen for analysis of the sample. If GC/MS is use d, the ion selectivity of the technique**  **may compensate for chromatographic interferences. There are three extraction procedures for solid sa**  **mples that employ supercritical fluid extraction (SFE). Method 3560 is a technique**  **for the extraction of petroleum hydrocarbons from various solid matrices using carb**  **on dioxide at elevated temperature and pressure. Method 3561 may be used to selective**  **ly extract polynuclear aromatic hydrocarbons (PAHs) from solid matrices using super**  **critical carbon dioxide and appropriate modifiers, based on the determinative p**  **rocedure to be used. Method 3562 may be used to selectively extract organochlorine p**  **esticides or PCBs from solid matrices using supercritical carbon dioxide.**  **2.3.1.3 Oils and organic liquids Method 3580, waste dilution, may be used to prepar**  **e oils and organic liquid samples for analysis of semivolatile and extractabl**  **e organic analytes by GC or GC/MS. Method 3585 may be employed for the preparation of**  **these matrices for volatiles analysis by GC or GC/MS. To avoid overloading the analytica**  **l detection system, care must be exercised to ensure that proper dilutions are made.**  **Methods 3580 and 3585 give guidance on performing waste dilutions.** 
**To remove interferences for semivolatiles and extr actables, Method 3611 (alumina**  **cleanup) may be performed on an oil sample directly , without prior sample preparation.**  **Method 3650 is the only other preparative procedur e for oils and other organic**  **liquids. This procedure is a back extraction into an aqueous phase. It is generally**  **introduced as a cleanup procedure for extracts rath er than as a preparative procedure.**  **Oils generally have a high concentration of semivol atile compounds and, therefore,**  **preparation by Method 3650 should be done on a rela tively small aliquot of the sample.**  **Generally, extraction of 1 mL of oil will be suffic ient to obtain a saturated aqueous phase**  **and avoid emulsions. SW-846 Update V TWO - 8 Revision 5**  **July 2014 NOTE: The use of traditional extraction technique**  **s (i.e., 3510, 3520, 3535, 3540, 3541,**

**3545, 3546, and 3550), is neither suitable nor reco mmended for use in these**  **matrices due to a high potential for hydrocarbon in terferences and decreased**  **determinative method sensitivity (i.e., poor analyt ical performance).**  **2.3.1.4 Sludge samples Determining the appropriate methods for analysis**  **of sludges is complicated because of the lack of precise definitions of sludg**  **es with respect to the relative percent of liquid and solid components. There is no set ratio**  **of liquid to solid that enables the analyst to determine which of the three extraction methods**  **cited is the most appropriate. Sludges may be classified into three categories: liquid sl**  **udges, solid sludges, and emulsions, but with appreciable overlap.**  **If the sample is an organic sludge (solid material and organic liquid, as opposed to**  **an aqueous sludge), the sample should be handled as a multiphase sample.** 

**2.3.1.4.1 Liquid sludges Method 3510 or Method 3520 may be applicable to s**  **ludges that behave like, and have the consistency of, aqueous liquids.**  **Ultrasonic extraction (Method 3550) and Soxhlet-type (Method 3540 series) procedu**  **res will, most likely, be ineffective because of the overwhelming presence of**  **the liquid aqueous phase. 2.3.1.4.2 Solid sludges**  **Soxhlet extraction (Methods 3540 and 3541), press urized fluid extraction**  **(Method 3545), microwave extraction (Method 3546), and ultrasonic extraction**  **(Method 3550) will be more effective when applied t o sludge samples that**  **resemble solids. Samples may be dried or centrifug ed to form solid materials for**  **subsequent determination of semivolatile compounds. Using Method 3650, Acid-Base Partition Cleanup, on**  **the extract may be necessary, depending on whether chromatographic int**  **erferences prevent determination of the analytes of interest.** 
**2.3.1.4.3 Emulsions Attempts should be made to break up and separate**  **the phases of an emulsion. Several techniques are effective in brea**  **king emulsions or separating the phases of emulsions, including:**  **1. Freezing/thawing -- Certain emulsions will sepa rate if exposed to** 

**temperatures below 0 °C. 2. Salting out -- Addition of a salt to make the**  **aqueous phase of an emulsion too**

**polar to support a less polar phase promotes separa tion.**  **3. Centrifugation -- Centrifugal force may separat e emulsion components by** 

**density. SW-846 Update V TWO - 9 Revision 5**  **July 2014 4. Addition of water or ethanol -- Emulsion polym**  **ers may be destabilized when a**

**preponderance of the aqueous phase is added. 5. Forced filtering through glass wool -- Many emul**  **sions can be broken by forcing the emulsion through a pad of Pyrex glass w**  **ool in a drying column using a slight amount of air pressure (using a rubb**  **er bulb usually provides sufficient pressure).**  **If techniques for breaking emulsions fail, use Me thod 3520. If the**  **emulsion can be broken, the different phases (aqueo us, solid, or organic liquid)**  **may then be analyzed separately. 2.3.1.5 Multiphase samples**  **Choice of the procedure for separating multiphase samples is highly dependent on**  **the objective of the analysis. With a sample in wh ich some of the phases tend to separate**  **rapidly, the percent weight or volume of each phase should be calculated and each phase**  **should be individually analyzed for the required an alytes.**  **An alternate approach is to obtain a homogeneous s ample and attempt a single**  **analysis on the combination of phases. This approa ch will give no information on the**  **abundance of the analytes in the individual phases other than what can be implied by**  **solubility. A third alternative is to select phases of interes**  **t and to analyze only those selected phases. This tactic must be consistent with the sa**  **mpling/analysis objectives or it will yield insufficient information for the time and resources**  **expended. The phases selected should be compared with Figure 2-1 and Table 2-41 for furt**  **her guidance. 2.3.2 Cleanup procedures**  **Cleanup procedure selection is determined by the a nalytes of interest within the extract.**  **Each analyte type in Table 2-42, Cleanup Methods fo r Organic Analyte Extracts, corresponds to**  **one or more of the possible determinative methods a vailable in the manual. However, the**  **necessity of performing cleanup may also depend upo n the matrix from which the extract was**  **developed. Cleanup of a sample may be done exactly as instructed in the cleanup method for**  **some of the analytes. There are some instances whe n cleanup using one of the methods may**  **only proceed after the procedure is modified to opt imize recovery and separation. Several**  **cleanup techniques may be possible for each analyte category. The information provided is not**  **meant to imply that any or all of these methods mus t be used for the analysis to be acceptable.**  **Extracts with components which interfere with spect ral or chromatographic determinations are**  **expected to be subjected to cleanup procedures. The analyst, in consultation with the regulator, c**  **ustomer, and other project planning participants as necessary, must determine the neces**  **sity for cleanup procedures, as there are no clear-cut criteria for indicating their use. Me**  **thod 3600 and associated methods should be consulted for further details on extract cleanup.** **SW-846 Update V TWO - 10 Revision 5 July 2014**  **2.3.3 Determinative procedures In Table 2-43, the determinative methods for organ**  **ic analytes are divided into four categories, specifically: GC/MS (this category inc**  **ludes single quadrupole MS, triple quadrupole (MS/MS), and time-of-flight instruments); GC with e**  **lectromagnetic spectrometric (ES) detectors (i.e., Fourier Transform infrared (FT-IR) or atomic**  **emission (AES)); specific quantitation methods (i.e., GC with specific non-MS detectors);**  **and HPLC, including any HPLC-MS methods. This division is intended to help an anal**  **yst choose which determinative method will apply. Under each analyte column, SW-846 method nu**  **mbers are indicated, if appropriate, for the determination of the analyte. A blank has been**  **left if no chromatographic determinative method is available.**  **Generally, the MS procedures are more specific but less sensitive than the appropriate**  **gas chromatographic/specific quantitation or ES met hod.**  **Method 8000 gives a general description of the tec hniques of GC and HPLC. Method**  **8000 should be consulted prior to application of an y of the GC or HPLC methods.**  **Method 8081 (organochlorine pesticides), Method 80 82 (PCBs), Method 8141**  **(organophosphorus pesticides), and Method 8151 (chl orinated herbicides), are preferred over**  **GC/MS because of the combination of selectivity and sensitivity of the flame photometric,**  **nitrogen-phosphorus, and electron capture detectors**

**. Method 8260 is a GC/MS method for volatile analyte**  **s. A variety of sample introduction techniques may be used with Method 8260, including**  **Methods 5021, 5030, 5031, 5035, 5041, and 3585. A GC with a selective detector is also u**  **seful for the determination of volatile organic compounds in a monitoring scenario, as described in**  **Sec. 2.2.5.**
**Method 8270 is a GC/MS method for semivolatile ana lytes. Method 8410 is another GC**  **method for semivolatile analytes which uses a FT-IR detector. Method 8085 is a GC method for**  **pesticides which uses an AES detector.**
**Table 2-43 lists several GC and HPLC methods that apply to only a small number of**  **analytes. Methods 8031 and 8033 are GC methods for acrolein, acrylonitrile, and acetonitrile.**  **Methods 8315 and 8316 are HPLC methods for these th ree analytes. Method 8316 also**  **addresses acrylamide, which may be analyzed by Meth od 8032. Method 8325 is an HPLC**  **coupled with particle beam MS for the determination of benzidines and**  **nitrogen-containing pesticides in water and wastewa ter. Method 8520 measures formaldehyde**  **in ambient air primarily for non-occupational expos ure monitoring. Method 8540 is used for**  **field-testing of soil samples for pentachlorophenol (PCP).**  **HPLC methods have been developed for other types o f analytes, most notably N-methyl**  **carbamates (Method 8318); azo dyes, phenoxy acid he rbicides, carbamates, and**  **organophosphorus pesticides (Method 8321); PAHs (Me thod 8310); explosives (Methods 8330,**  **8331, and 8332); and some volatile organics (Method s 8315 and 8316).**  **Method 8430 utilizes a FT-IR spectrometer coupled to a gas chromatograph to determine**  **bis(2-chloroethyl) ether and its hydrolysis product s. The sample is introduced by direct aqueous**  **injection. Method 8440 may be employed for the det ermination of total recoverable petroleum**  **hydrocarbons (TRPH) in solid samples by infrared (I R) spectrophotometry. The samples may**  **be extracted with supercritical carbon dioxide, usi ng Method 3560.** **SW-846 Update V TWO - 11 Revision 5 July 2014**  **2.4 CHOOSING PROCEDURES FOR CHARACTERISTIC ANALYSES 2.4.1 Figure 2-2 outlines a sequence for determini**  **ng if a waste exhibits one or more of the characteristics of a hazardous waste.** 
**2.4.2 SPLP, EP and TCLP extracts The leachate obtained from using either the Synthe**  **ntic Precipitation Leaching procedure (SPLP), EP (Figure 2-3A) or the TCLP (Figure 2-3B)**  **is an aqueous sample, and therefore, requires further solvent extraction prior to the an**  **alysis of semivolatile compounds.**
**The SPLP or TCLP leachate is solvent extracted wit h methylene chloride at a pH <2 and**  **at a pH >11 by either Method 3510 or 3520. The lea chate may also be extracted as received**  **for organochlorine pesticides and semivolatiles and at pH <1.0 for phenoxyacid herbicides using**  **the solid phase extraction (SPE) disk option in Met hod 3535. The best recoveries are usually**  **obtained using either Method 3520 or Method 3535. The solvent extract obtained by performing either**  **Method 3510 or 3520 at an acidic pH will contain the acid/neutral compounds of interest. Re**  **fer to the specific determinative method for guidance on the pH requirements for extraction prio**  **r to analysis. Method 5031 (azeotropic distillation) may be used as an effective preparati**  **ve method for pyridine. Due to the high concentration of acetate in the TC**  **LP extract, it is recommended that purge-and-trap be used to introduce the volatile sa**  **mple into the gas chromatograph. The SPLP, EP and/or TCLP extracts can also be diges**  **ted using acids (Method 3010, 3015, or 3020) and analyzed for metals using a 6000 or 7000**  **series method (Figures 2-3A and 2-3B).**

**2.5 CHOOSING PROCEDURES FOR GROUNDWATER ANALYSES Appropriate analysis schemes for the determination**  **of analytes in groundwater are presented in Figures 2-4A, 2-4B, and 2-4C. Quantit**  **ation limits (LLOQs) for the inorganic analytes should correspond to the drinking water li**  **mits, where such limits are available. 2.5.1 Special techniques for inorganic analytes**  **All atomic absorption (AA) analyses should employ appropriate background correction**  **systems whenever spectral interferences could be pr esent. Several background correction**  **techniques are employed in modern AA spectrometers. Matrix modification can complement**  **background correction in some cases. Since no appr oach to interference correction is**  **completely effective in all cases, the analyst shou ld attempt to verify the adequacy of correction.**  **If the interferant is known (e.g., high concentrati ons of iron in the determination of selenium),**  **accurate analyses of synthetic solutions of the int erferant (with and without analyte) could**  **establish the efficacy of the background correction . If the nature of the interferant is not**  **established, good agreement of analytical results u sing two substantially different wavelengths**  **could substantiate the adequacy of the background c orrection.** **SW-846 Update V TWO - 12 Revision 5 July 2014**  **To reduce matrix interferences, all graphite furna ce atomic absorption (GFAA) analyses**  **should be performed using techniques which maximize an isothermal environment within the**  **furnace cell. Data indicate that two such techniqu es, L'vov platform and the delayed**  **atomization cuvette (DAC), are equivalent in this r espect, and produce high quality results.**  **All GFAA analysis should be carried out using the best matrix modifier for the analysis.**  **Some examples of modifiers are listed below. (See also the appropriate methods.)** 

**Element(s) Modifier(s) As and Se Nickel nitrate, palladium**  **Pb Phosphoric acid, ammonium phosphate, palladium Cd Ammonium phosphate, palladium**  **Sb Ammonium nitrate, palladium Tl Platinum, palladium** 
**Inductively coupled plasma (ICP), AA, and GFAA cal ibration standards need to match the**  **acid composition and strength of the acids containe d in the samples. Acid strengths of the**  **calibration standards should be stated in the raw d ata. When using a method which permits the**  **use of internal standardization, and the internal s tandardization option is being used, matrix**  **matching is not required.**
**2.6 CHOOSING PROCEDURES FOR INORGANIC ANALYSES Methods for preparing different sample matrices fo**  **r inorganic analyses are shown in Table 2-44. Guidance regarding the use of leaching and d**  **igestive methods for inorganic analysis is provided in Table 2-45.**
