QUALIFIERS
Project: 22011224-WS
Pace Project No.: 92582688
DEFINITIONS
OF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
H 1 Analysis conducted outside the EPA method holding time.
IH This analyte exceeded secondary source verification criteria high for the initial calibration.The reported results should be
considered an estimated value.
IL This analyte exceeded secondary source verification criteria low for the initial calibration.The reported results should be
considered an estimated value.
L1 Analyte recovery in the laboratory control sample(LCS)was above QC limits. Results for this analyte in associated
samples may be biased high.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.

QUALIFIERS
Project: 22041312-WS
Pace Project No.: 92599488
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenyfamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
BC The same analyte was detected in an associated blank at a concentration above 1/2 the reporting limit but below the
laboratory reporting limit.
E Analyte concentration exceeded the calibration range.The reported result is estimated.
L1 Analyte recovery in the laboratory control sample(LCS)was above QC limits. Results for this analyte in associated
samples may be biased high.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.

ANALYTE QUALIFIERS
2g Due to a power outage on 7/12/22,the temperature of the refrigerated storage unit holding samples waiting preparation
and analysis exceeded the acceptance range of 0-6C. The maximum temperature recording during this time frame was
19.6C.
L1 Analyte recovery in the laboratory control sample(LCS)was above QC limits. Results for this analyte in associated
samples may be biased high.
L2 Analyte recovery in the laboratory control sample(LCS)was below QC limits. Results for this analyte in associated
samples may be biased low.
