**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 which contain 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 QC acceptance 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 trace analytical methods to**  **demonstrate that a waste does not contain analytes of concern that cause it to be managed as**  **a hazardous waste. As such, these methods typicall y contain relatively stringent recommended**  **quality control (QC) criteria appropriate to trace analyses. However, if a particular application**  **does not require data of this quality, less stringe nt 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 information regarding choosing procedures for inorg**  **anic analyte analyses. Tables and figures referenced in this chapter are sequentially located**  **after the last page chapter text. SW-846 Update V TWO - 2**  **Revision 5 October 2012**  **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 RCRA application has b**  **een documented. Such performance includes consideration of precision, accuracy (or b**  **ias), recovery, representativeness, comparability, and sensitivity (quantitation or rep**  **orting limits) relative to the data quality objectives for the intended use of the analytical r**  **esults. In response to this inherent flexibility, if**  **an alternative analytical procedure is employed, th en EPA expects the laboratory to**  **demonstrate and document that the procedure is capa ble of providing appropriate performance**  **for its intended application. This demonstration m ust not be performed after the fact, but as part**  **of the laboratory’s initial demonstration of profic iency with the method. The documentation**  **should be in writing, maintained in the laboratory, and available for inspection upon request by**  **authorized representatives of the appropriate regul atory authorities. The documentation should**  **include the performance data as well as a detailed description of the procedural steps as**  **performed (i.e., a written standard operating proce dure).**  **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 other metho**  **ds. 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**  **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** **SW-846 Update V TWO - 3 Revision 5**  **October 2012 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 data quality objectives 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 u**  **sed in the methods for QC purposes, such as surrogates, internal standards, system performance**  **check compounds, etc. Additional analytes, not included on the analyte list of a par**  **ticular method(s) but needed for a specific project, may be analyzed by that particular method(**  **s), if appropriate performance can be demonstrated for the analytes of concern in the mat**  **rices of concern at the levels 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. elimination of concentration steps prescribed fo r "trace" analyses, and**  **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 October 2012**  **Chapter One contains general quality control (QC) guidance for analyses using SW-846**  **methods. QC guidance specific to a given analytica l technique (e.g., extraction, cleanup,**  **sample introduction, or analysis) may be found in M ethods 3500, 3600, 5000, 7000, and 8000.**  **Method-specific QC criteria may be found in Sec. 8. 0 of most older individual methods, in Sec.**  **9.0 of newer methods, or in Sec. 11.0 of some air s ampling methods. When inconsistencies**  **exist between the information in these locations, m ethod-specific QC criteria take precedence**  **over both technique-specific criteria and those cri teria given in Chapter One, and technique**  **specific QC criteria take precedence over the crite ria in Chapter 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:**  **-The physical state of the sample -The analytes of interest**  **-The sensitivity or quantitation limits needed -The analytical objective**  **-Whether the purpose is quantitation or monitoring -What sample containers and preservation will be us**  **ed 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 Stack Sampling (VOST) Condensate**  **TCLP or EP Extract Multiphase Sample Solid**  **Groundwater 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 which**  **are used to identify and quantify them. The most b asic differentiation is between organic (e.g.,**  **carbon-containing) analytes and inorganic (e.g., me tals and 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.**  **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.** **SW-846 Update V TWO - 5 Revision 5**  **October 2012 2.2.3 Sensitivity or quantitation limits**  **Some regulations may require a specific sensitivit y or quantitation limit for an analysis, as**  **in the determination of analytes for the Toxicity C haracteristic (TC). Drinking water quantitation**  **limits, for those specific organic and metallic ana lytes covered by the National Primary Drinking**  **Water Regulations, are desired in the analysis of g roundwater.**  **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., GC/MS or HPLC/MS), it may be necessa**  **ry to employ a more sensitive quantitation method (e.g., electron capture). In t**  **hese instances, the risk of false positive results may be minimized by confirming the results through**  **a second analysis with a dissimilar detector or chromatographic column. Thus, the choice of tec**  **hnique for organic analytes may be governed by the quantitation limit requirements and**  **potential interferants. Similarly, the choice of technique for metals is g**  **overned by the quantitation limit requirements and potential interferants.**  **In contrast, monitoring samples are analyzed to co nfirm existing and on-going 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 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 SW-846 Update V TWO - 6**  **Revision 5 October 2012**  **a constituent to be above the regulatory threshold, but cannot be used to demonstrate that a**  **waste is not hazardous. However, regarding the information 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 from aqueous samples. The choice**  **of a preparative method depends on the sample. Method 3510, a separatory funnel li**  **quid-liquid extraction technique, is appropriate for samples which will not form a persi**  **stent emulsion interface between the sample and the extraction solvent. The formation o**  **f an emulsion that cannot be broken up by mechanical techniques will prevent proper extrac**  **tion 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** 

**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** **SW-846 Update V TWO - 7 Revision 5**  **October 2012 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 GC method is chosen for analysis of**  **the sample. If GC/MS is used, 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 analytical**  **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.**
**NOTE : The use of traditional extraction techniques, i.**  **e., 3510, 3520, 3535, 3540, 3541,**

**3545, 3546, and 3550, is neither suitable nor recom mended for use in these** **SW-846 Update V TWO - 8 Revision 5**  **October 2012 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 which enables the**  **analyst to determine which of the three extraction methods cited is the most appropriate.**  **Sludges may be classified into three categories: l iquid sludges, 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 (Method**  **3545) extraction, 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. 4. Addition of water or ethanol -- Emulsion polym**  **ers may be destabilized when a**

**preponderance of the aqueous phase is added. SW-846 Update V TWO - 9**  **Revision 5 October 2012**  **5. Forced filtering through glass wool -- Many emul sions can be broken by**  **forcing the emulsion through a pad of Pyrex glass wool 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, cu stomer and other project planning**  **participants, as necessary, must determine the nece ssity 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 October 2012**  **2.3.3 Determinative procedures In Table 2-43, the determinative methods for organ**  **ic analytes are divided into four categories, specifically: gas chromatography/mass**  **spectrometry (GC/MS); gas chromatography (GC) with electromagnetic spectromet**  **ric (ES) detectors, i.e., Fourier Transform infrared (FT-IR) or atomic emission (AES); specific**  **quantitation methods, i.e., gas chromatography (GC) with specific non-MS detectors;**  **and high performance liquid chromatography (HPLC). This division is intended t**  **o help an analyst choose which determinative method will apply. Under each analyt**  **e column, SW-846 method numbers 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 gas chromatography and**  **high performance liquid chromatography. Method 800 0 should be consulted prior to application**  **of any of the gas chromatographic methods. Method 8081 (organochlorine pesticides), Method 80**  **82 (polychlorinated biphenyls), Method 8141 (organophosphorus pesticides), and Meth**  **od 8151 (chlorinated herbicides), are preferred over GC/MS because of the combination of**  **selectivity and sensitivity of the flame photometric, nitrogen-phosphorus, and electron capt**  **ure detectors. Method 8260 is a GC/MS method for volatile analyte**  **s, which employs a capillary column. 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 useful for the determination of volatile organic compounds in a mo**  **nitoring scenario, as described in Sec. 2.2.5.** 
**Method 8270 is a GC/MS method for semivolatile ana lytes, which employs a capillary**  **column. Method 8410 is another capillary GC method for semivolatile analytes which uses a**  **Fourier Transform IR (FT-IR) detector. Method 8085 is a capillary GC method for pesticides**  **which uses an atomic emission detector (AES).**
**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.**  **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 fourier transform infrared spectrometer (FT-IR) coupled to a gas**  **chromatograph to determine bis(2-chloroethyl) ether and its hydrolysis products. The sample is**  **introduced by direct aqueous injection. Method 844 0 may be employed for the determination of**  **total recoverable petroleum hydrocarbons (TRPH) in solid samples by infrared (IR)** **SW-846 Update V TWO - 11 Revision 5**  **October 2012 spectrophotometry. The samples may be extracted wi**  **th supercritical carbon dioxide, using Method 3560.** 

**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 EP and TCLP extracts The leachate obtained from using either the EP (Fi**  **gure 2-3A) or the TCLP (Figure 2-3B) is an aqueous sample, and therefore, requires further**  **solvent extraction prior to the analysis of semivolatile compounds.**  **The TCLP leachate is solvent extracted with methyl ene chloride at a pH <2 and at a pH**  **>11 by either Method 3510 or 3520. The leachate ma y 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 EP and TCLP extracts can also be digested usin**  **g 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 for the inorganic analytes should correspond to the drinking water limits, where such**  **limits are available. 2.5.1 Special techniques for inorganic analytes**  **All atomic absorption analyses should employ appro priate background correction systems**  **whenever spectral interferences could be present. Several background correction techniques**  **are employed in modern atomic absorption spectromet ers. 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**  **October 2012 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 furnace atomic absorption analysis should be c**  **arried out using the best matrix modifier for the analysis. Some examples of modifiers are l**  **isted 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**

**ICP, AA, and GFAA calibration standards need to ma tch the acid composition and**  **strength of the acids contained in the samples. Ac id strengths of the calibration standards**  **should be stated in the raw data. When using a met hod which permits the use of internal**  **standardization, and the internal standardization o ption 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.**
