2. SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack. Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010.
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18. Detailed test results summaries are provided in Section 6.
It is important to note that emphasis is being placed on the characterization of the emissions
based on the M0010 stack test results. Research conducted in developing the protocol for stack
testing HFPO Dimer Acid Fluoride, HFPO Dimer Acid Ammonium Salt and HFPO Dimer Acid
realized that the resulting testing, including collection of the air samples and extraction of thevarious fraction of the sampling train, would result in all three compounds being expressed as
simply the HFPO Dimer Acid. However, it should be understood that the total M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of thethree compounds.

3. PROCESS DESCRIPTIONSThe Fluoromonomers area is included in the scope of this test program.
3.1 FLUOROMONOMERS
These facilities produce a family of fluorocarbon compounds used to produce Chemours
products such as Nafion®, Krytox®, and Viton®, as well as sales to outside customers.
At the time of testing, process emissions were vented to the Division waste gas scrubber system(which included the secondary scrubber) and vented to the Carbon Bed and then into theDivision stack. The VE North building air systems were vented to the Carbon Bed and then into
the Division stack.

4. DESCRIPTION OF TEST LOCATIONS
4.1 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below. The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which,under normal process operations, do not discharge to the stack. They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance.
Per EPA Method 1, a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling. Figure 4-1 provides a schematic of the test ports and traverse point locations.

5. SAMPLING AND ANALYTICAL METHODS
5.1 STACK GAS SAMPLING PROCEDURES
The purpose of this section is to describe the stack gas emissions sampling trains and to provide
details of the stack sampling and analytical procedures utilized during the emissions test
program.
5.1.1 Pre-Test Determinations
Preliminary test data were obtained at the test location. Stack geometry measurements were
measured and recorded, and traverse point distances verified. A preliminary velocity traverse
was performed utilizing a calibrated S-type pitot tube and an inclined manometer to determine
velocity profiles. Flue gas temperatures were observed with a calibrated direct readout panel
meter equipped with a chromel-alumel thermocouple. Preliminary water vapor content wasestimated by wet bulb/dry bulb temperature measurements.
A check for the presence or absence of cyclonic flow was previously conducted at the test
location. The cyclonic flow check was negative (< 20°) verifying that the test location was
acceptable for testing.
Preliminary test data was used for nozzle sizing and sampling rate determinations for isokinetic
sampling procedures.
Calibration of probe nozzles, pitot tubes, metering systems, and temperature measurement
devices was performed as specified in Section 5 of EPA Method 5 test procedures.
5.2 STACK PARAMETERS
5.2.1 EPA Method 0010
The sampling train utilized to perform the HFPO Dimer Acid sampling at the location was an
EPA Method 0010 train (see Figure 5-1). The Method 0010 consisted of a borosilicate nozzle
that attached directly to a heated borosilicate probe. In order to minimize possible thermal
degradation of the HFPO Dimer Acid, the probe and particulate filter were heated above stacktemperature to minimize water vapor condensation before the filter. The probe was connected
directly to a heated borosilicate filter holder containing a solvent extracted glass fiber filter.

A section of borosilicate glass or flexible polyethylene tubing connected the filter holder exit to a
Grahm (spiral) type ice water-cooled condenser, an ice water-jacketed sorbent module containing
approximately 40 grams of XAD-2 resin. The XAD-2 resin tube was equipped with an inlet
temperature sensor. The XAD-2 resin trap was followed by a condensate knockout impinger anda series of two impingers that contained 100 mL of high-purity distilled water. The train also
included a second XAD-2 resin trap behind the impinger section to evaluate possible sampling
train breakthrough. Each XAD-2 resin trap was connected to a 1-liter condensate knockout trap.
The final impinger contained 300 grams of dry pre-weighed silica gel. All impingers and thecondensate traps were maintained in an ice bath. Ice water was continuously circulated in thecondenser and the XAD-2 module to maintain method-required temperature. A control consolewith a leakless vacuum pump, a calibrated orifice, and dual inclined manometers was connectedto the final impinger via an umbilical cord to complete the sample train.
HFPO Dimer Acid Fluoride (CAS No. 2062-98-8) that is present in the stack gas is expected tobe captured in the sampling train along with HFPO Dimer Acid (CAS No. 13252-13-6). HFPO
Dimer Acid Fluoride underwent hydrolysis instantaneously in water in the sampling train andduring the sample recovery step, and was converted to HFPO Dimer Acid such that the amountof HFPO Dimer Acid emissions represented a combination of both HFPO Dimer Acid Fluoride
and HFPO Dimer Acid.
During sampling, gas stream velocities were measured by attaching a calibrated S-type pitot tube
into the gas stream adjacent to the sampling nozzle. The velocity pressure differential wasobserved immediately after positioning the nozzle at each traverse point, and the sampling rateadjusted to maintain isokineticity at 100% ± 10. Flue gas temperature was monitored at eachpoint with a calibrated panel meter and thermocouple. Isokinetic test data was recorded at eachtraverse point during all test periods, as appropriate. Leak checks were performed on thesampling apparatus according to reference method instructions, prior to and following each run,component change (if required) or during midpoint port changes.
5.2.2 EPA Method 0010 Sample Recovery
At the conclusion of each test, the sampling train was dismantled, the openings sealed, and thecomponents transported to the field laboratory trailer for recovery.
A consistent procedure was employed for sample recovery:

1. The two XAD-2 covered (to minimize light degradation) sorbent modules (1 and 2) weresealed and labeled.
2. The glass fiber filter(s) were removed from the holder with tweezers and placed in apolyethylene container along with any loose particulate and filter fragments.
3. The particulate adhering to the internal surfaces of the nozzle, probe and front half of thefilter holder were rinsed with a solution of methanol and ammonium hydroxide into apolyethylene container while brushing a minimum of three times until no visible
particulate remained. Particulate adhering to the brush was rinsed with methanol/ammonium hydroxide into the same container. The container was sealed.
4. The volume of liquid collected in the first condensate trap was measured, the value
recorded, and the contents poured into a polyethylene container.
5. All train components between the filter exit and the first condensate trap were rinsed withmethanol/ammonium hydroxide. The solvent rinse was placed in a separate polyethylene
container and sealed.
6. The volume of liquid in impingers one and two, and the second condensate trap, were
measured, the values recorded, and the sample was placed in the same container as Step 4
above, then sealed.
7. The two impingers, condensate trap, and connectors were rinsed with methanol/ammonium hydroxide. The solvent sample was placed in a separate polyethylene
container and sealed.
8. The silica gel in the final impinger was weighed and the weight gain value recorded.
9. Site (reagent) blank samples of the methanol/ammonium hydroxide, XAD resin, filterand distilled water were retained for analysis.
Each container was labeled to clearly identify its contents. All samples were maintained cool.
Following sample recovery, all samples were transported to Eurofins TestAmerica(TestAmerica) for sample extraction and analysis.
See Figure 5-2 for a schematic of the Method 0010 sample recovery process.

5.2.3 EPA Method 0010 Sample Analysis
Method 0010 sampling trains resulted in four separate analytical fractions for HFPO Dimer Acid
analysis according to SW-846 Method 3542:


Front-half Composite—comprised of the particulate filter, and the probe, nozzle, andfront-half of the filter holder solvent rinses;

Back-half Composite—comprised of the first XAD-2 resin material and the back-half ofthe filter holder with connecting glassware solvent rinses;Condensate Composite—comprised of the aqueous condensates and the contents ofimpingers one and two with solvent rinses;



Breakthrough XAD-2 Resin Tube—comprised of the resin tube behind the series ofimpingers.

The second XAD-2 resin material was analyzed separately to evaluate any possible sampling
train HFPO-DA breakthrough.
The front-half and back-half composites and the second XAD-2 resin material were placed inpolypropylene wide-mouth bottles and tumbled with methanol containing 5% NH4OH for 18
hours. Portions of the extracts were processed analytically for the HFPO dimer acid by liquid
chromatography and duel mass spectroscopy (HPLC/MS/MS). The condensate composite wasconcentrated onto a solid phase extraction (SPE) cartridge followed by desorption from the
cartridge using methanol. Portions of those extracts were also processed analytically by
HPLC/MS/MS.

preparation to provide accurate assessments of the analytical recoveries. Final data was corrected
for IDA standard recoveries.
TestAmerica developed detailed procedures for the sample extraction and analysis for HFPO
Dimer Acid. These procedures were incorporated into the test protocol.
5.3 MM18
The sampling train utilized to perform the target compound sampling at the Division stack was amodified EPA Method 18 train using full size Teflon® impingers. Impingers 1 through 6 eachcontained 100 mL of methanol. See Figure 5-3 for the modified EPA Method 18 sampling train.
The impingers were maintained in a dry ice/methanol bath. Each test run was approximately 90
minutes in duration collecting at a rate of approximately ≥1.5 liters per minute.
Each impinger was recovered and included a methanol rinse of each impinger and connector.
The impinger contents and rinses were collected separately.
Each sample was analyzed by EPA SW-846 Method 8260B and 8231A procedures by Gas
Chromatography (GC) Mass Spectrometry (MS).
During the Division stack test campaign, a blank train was set up near the test location, leakchecked and recovered along with the respective sample train. Following sample recovery, allsamples were transported to TestAmerica for sample extraction and analysis.

5.4 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations. A diagram of the Weston sampling system ispresented in Figure 5-4.
For the Division stack test campaign, the sample was collected at the exhaust of the Method0010 sampling system. At the end of the line, a tee permitted the introduction of calibration gas.
The sample was drawn through a heated Teflon® sample line to the sample conditioner. The
output from the sampling system was recorded electronically, and one minute averages wererecorded and displayed on a data logger.
Each analyzer was set up and calibrated internally by introduction of calibration gas standards
directly to the analyzer from a calibration manifold. The calibration manifold is designed with anatmospheric vent to release excess calibration gas and maintained the calibration at ambientpressure. The direct calibration sequence consisted of alternate injections of zero and mid-range
gases with appropriate adjustments until the desired responses were obtained. The high-range
standards were then introduced in sequence without further adjustment.
The sample line integrity was verified by performing a bias test before and after each test period.
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally. The
excess calibration gas flowed out through the probe to maintain ambient sampling systempressure. Calibration gas supply was regulated to maintain constant sampling rate and pressure.
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of themeasured concentration of the bias gas certified by the calibration gas supplier.
The oxygen and carbon dioxide content of each stack gas was measured according to EPA
Method 3A procedures which incorporate the latest updates of EPA Method 7E. A Servomex
Model 4900 analyzer (or equivalent) was used to measure oxygen content. A Servomex Model
4900 analyzer (or equivalent) was used to measure carbon dioxide content of the stack gas. Bothanalyzers were calibrated with EPA Protocol gases prior to the start of the test program andperformance was verified by sample bias checks before and after each test run.

M0010 test run number two was stopped prior to the full run time due to a process upset in thearea. The run was considered complete and the sample was recovered and submitted for analysis.
A total of two M0010 test runs were performed at the location. A total of three MM18 test runs
were performed at the location.
Table 6-1 provides detailed M0010 test data and test results for Division stack. Table 6-2
provides detailed MM18 test data and test results for the Division stack.
The Method 3A sampling indicated that the O2 and CO2 concentrations were at ambient air
levels (20.9% O2, 0% CO2), therefore, 20.9% O2 and 0% CO2 values were used in all
calculations.
It should be noted that methylene chloride was identified in the MM18 analytical results. Thisdetection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing. Methylene chloride
would not typically be detected in this process area.

Job Narrative
140-17458-1
Sample Receipt
The samples were received on November 25, 2019 at 8:00 AM in good condition and properly preserved. The temperature of the cooler
at receipt was 1.6º C.
Quality Control and Data Interpretation
Unless otherwise noted, all holding times, and QC criteria were met and the test results shown in this report meet all applicable NELAC
requirements.
Method 0010/Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmerica’s Knoxville laboratory. Extracts and condensate samples were
forwarded to the Denver laboratory for HFPO-DA analysis. All results are reported in “Total ug” per sample.
LCMS
Method 8321A: The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory.
·
DIV VEN Stack R1 FH·
DIV VEN Stack R1 BH·
DIV VEN R1 Breakthrough·DIV VEN Stack R2 FH·
DIV VEN Stack R2 BH·
DIV VEN R2 BreakthroughAs a result, these samples received a relatively small fortification of the native HFPO-DA, and no labeled IDA as typically applied. Upon
discovery of the processing issue, the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples. The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA,
and the corrected concentration is reported in with the data set below.
Please note that under these conditions, the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction. However, the HFPO-DA concentrations are accurate and useful for their intended purpose.
Method 8321A: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for preparation batch
280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes: HFPO. These analytes werebiased high in the LCS and were not detected in the associated samples; therefore, the data have been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Organic Prep
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

Job Narrative
140-17461-1
Sample Receipt
The samples were received on November 25, 2019 at 8:00 AM in good condition and properly preserved. The temperature of the cooler
at receipt was 1.6º C.
GC/MS VOA
Impinger Sample Preparation and Analysis: Impinger samples were analyzed for the volatile organic target analytes by purge and trap
GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015, based on the following method:·

SW-846 8260B, “Volatile Organic Compounds by Gas Chromatography/ Mass Spectrometry (GC/MS)”

Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal
standards, surrogates, and matrix spike analytes (as needed). Volatile compounds are introduced into the gas chromatograph by thepurge and trap method. The components are separated using the chromatograph and detected using a mass spectrometer, which
provides both qualitative and quantitative information.
Impinger sample results were calculated using the following equation:
Concentration, μg/sample = (C × DF × W × Vt) / (Va)
Where:C = On-column concentration, μg/L
DF = Dilution factor
W = Volume of water purged, L
Vt = Methanol extract final volume, μL
Va = Volume of extract analyzed, µL
Method 8260B: The LCS (LCS 140-35706/1-A) for analytical batch 140-35903 recovered below marginal exceedance limits for
Trichlorofluoromethane. This is an ongoing instrument issue with LCS recoveries for this analyte. The project manager approved moving
forward with analysis for the current job.
Method 8260B: The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems: Y-2972
R2 VEN DIV STACK MM18 IMPINGER #3 (140-17461-9), Y-2973 R2 VEN DIV STACK MM18 IMPINGER #4 (140-17461-10), Y-2974 R2
VEN DIV STACK MM18 IMPINGER #5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER #6 (140-17461-12).
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Total Halogens: The samples were prepared for total fluorine, chlorine, bromine and/or iodine using SOP number KNOX-WC-0016(based on ASTM Method E442 and SW-846 Method 5050). The sample is oxidized by combustion in an oxygen flask at atmosphericpressure or a bomb containing oxygen under pressure. The liberated halogen compounds are absorbed primarily as halides in a sodium
carbonate/sodium bicarbonate buffer solution. The combustion products are collected by repeated rinsing of the combustion apparatus,
and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056). The results arecalculated using the following equation:
C = [(Ccom × Vcom) / W] × 1000 g/Kg
Where:C = Concentration of analyte in the sample, mg/Kg
Ccom = Concentration of analyte in the combustate, mg/L
Vcom = Total volume of combustate, L
W = Weight of sample combusted, gAnions in Impinger Solutions: Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 300.0A and 9056).
The samples were diluted a minimum of 1/20 in ion chromatography solvent buffer solution to reduce the methanol concentration before
injection. Buffer concentrate was added until the pH was 10. Samples are diluted with ion chromatography eluate solution to bring theconcentrations within the calibration range when necessary. Higher dilutions are applied as necessary.
An aliquot of prepared sample is introduced into the ion chromatograph. Anions are identified based on their retention times as comparedto those of known standards. Quantification is accomplished by measuring the peak response and comparing it to a calibration curve
generated from known standards.

The pH of all samples were tested with pH paper. QC consisted of initial CCV and LCS which also serve as initial calibration, duplicate
analysis for every 10 samples, and closing CCV. A certified thermometer was used to check the ambient temperature.

Job Narrative
140-17557-1
Receipt
The samples were received on December 7, 2019 at 8:00 AM; the samples arrived in good condition, properly preserved and, whererequired, on ice. The temperatures of the 2 coolers at receipt time were 0.9º C and 1.4º C.
GC/MS VOA
Impinger Sample Preparation and Analysis: Impinger samples were analyzed for the volatile organic target analytes by purge and trap
GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015, based on the following method:·

SW-846 8260B, “Volatile Organic Compounds by Gas Chromatography/ Mass Spectrometry (GC/MS)”

Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal
standards, surrogates, and matrix spike analytes (as needed). Volatile compounds are introduced into the gas chromatograph by thepurge and trap method. The components are separated using the chromatograph and detected using a mass spectrometer, which
provides both qualitative and quantitative information.
Impinger sample results were calculated using the following equation:
Concentration, μg/sample = (C × DF × W × Vt) / (Va)
Where:C = On-column concentration, μg/L
DF = Dilution factor
W = Volume of water purged, L
Vt = Methanol extract final volume, μL
Va = Volume of extract analyzed, µL
Method 8260B: (LCS 140-35956/1-A) for analytical batch 140-35964 recovered below marginal exceedance limits for
Trichlorofluoromethane. This is an ongoing instrument issue with LCS recoveries for this analyte. The project manager approved moving
forward with analysis for the current job.
Method 8260B: The following samples were diluted to bring the concentration of target analytes within the calibration range: Y-2976 R3
VEN DIV STACK MM18 IMPINGER #1 (140-17557-1), Y-2977 R3 VEN DIV STACK MM18 IMPINGER #2 (140-17557-2), Y-2978 R3 VEN
DIV STACK MM18 IMPINGER #3 (140-17557-3), Y-2979 R3 VEN DIV STACK MM18 IMPINGER #4 (140-17557-4), Y-2980 R3 VEN DIVSTACK MM18 IMPINGER #5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER #6 (140-17557-6). Elevated reporting
limits (RLs) are provided.
Method 8260B: The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for
Chloroethane. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
General Chemistry
Total Halogens: The samples were prepared for total fluorine, chlorine, bromine and/or iodine using SOP number KNOX-WC-0016(based on ASTM Method E442 and SW-846 Method 5050). The sample is oxidized by combustion in an oxygen flask at atmosphericpressure or a bomb containing oxygen under pressure. The liberated halogen compounds are absorbed primarily as halides in a sodium
carbonate/sodium bicarbonate buffer solution. The combustion products are collected by repeated rinsing of the combustion apparatus,
and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056). The results arecalculated using the following equation:
C = [(Ccom × Vcom) / W] × 1000 g/Kg
Where:C = Concentration of analyte in the sample, mg/Kg
Ccom = Concentration of analyte in the combustate, mg/L
Vcom = Total volume of combustate, L
W = Weight of sample combusted, gAnions in Impinger Solutions: Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 300.0A and 9056).
The samples were diluted a minimum of 1/20 in ion chromatography solvent buffer solution to reduce the methanol concentration before
injection. Buffer concentrate was added until the pH was 10. Samples are diluted with ion chromatography eluate solution to bring thePage1038 of 706

12/30/2019

concentrations within the calibration range when necessary. Higher dilutions are applied as necessary.
An aliquot of prepared sample is introduced into the ion chromatograph. Anions are identified based on their retention times as comparedto those of known standards. Quantification is accomplished by measuring the peak response and comparing it to a calibration curve
generated from known standards.
The pH of all samples were tested with pH paper. QC consisted of initial CCV and LCS which also serve as initial calibration, duplicate
analysis for every 10 samples, and closing CCV. A certified thermometer was used to check the ambient temperature.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Job Narrative
140-17462-1
Sample Receipt
The samples were received on November 25, 2019 at 8:00 AM in good condition and properly preserved. The temperature of the cooler
at receipt was 3.3º C.
GC/MS VOA
Impinger Sample Preparation and Analysis: Impinger samples were analyzed for the volatile organic target analytes by purge and trap
GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015, based on the following method:·

SW-846 8260B, “Volatile Organic Compounds by Gas Chromatography/ Mass Spectrometry (GC/MS)”

Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal
standards, surrogates, and matrix spike analytes (as needed). Volatile compounds are introduced into the gas chromatograph by thepurge and trap method. The components are separated using the chromatograph and detected using a mass spectrometer, which
provides both qualitative and quantitative information.
Impinger sample results were calculated using the following equation:
Concentration, μg/sample = (C × DF × W × Vt) / (Va)
Where:C = On-column concentration, μg/L
DF = Dilution factor
W = Volume of water purged, L
Vt = Methanol extract final volume, μL
Va = Volume of extract analyzed, µL
Method 8260B: The following analyte(s) recovered outside control limits, but within marginal exceedance limits, for the LCS associatedwith batch 140-35880: Trichlorofluoromethane. This is not indicative of a systematic control problem because these were random
marginal exceedances. Qualified results have been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
LCMS
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
General Chemistry
Total Chlorine: The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 andSW-846 Method 5050). The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen
under pressure. The liberated halogen compounds are absorbed primarily as halides in a sodium carbonate/sodium bicarbonate buffer
solution. The combustion products are collected by repeated rinsing of the combustion apparatus, and analyzed by ion chromatography inaccordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056). The results are calculated using the following equation:
C = [(Ccom × Vcom) / W] × 1000 g/Kg
Where:C = Concentration of analyte in the sample, mg/Kg
Ccom = Concentration of analyte in the combustate, mg/L
Vcom = Total volume of combustate, L
W = Weight of sample combusted, gAnions in Impinger Solutions: Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 300.0A and 9056).
The samples were diluted a minimum of 1/20 in ion chromatography solvent buffer solution to reduce the methanol concentration before
injection. Buffer concentrate was added until the pH was 10. Samples are diluted with ion chromatography eluate solution to bring theconcentrations within the calibration range when necessary. Higher dilutions are applied as necessary.
An aliquot of prepared sample is introduced into the ion chromatograph. Anions are identified based on their retention times as comparedto those of known standards. Quantification is accomplished by measuring the peak response and comparing it to a calibration curve
generated from known standards.

The pH of all samples were tested with pH paper. QC consisted of initial CCV and LCS which also serve as initial calibration, duplicate
analysis for every 10 samples, and closing CCV. A certified thermometer was used to check the ambient temperature.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Organic Prep
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
