Page 16 of 21 I�Face", QUALIFIERS Project: MWs July 2023 Pace Project No.: 92676227 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. Pace Analytical Services, LLC 2225 Riverside Dr. Asheville, NC 28804 (828)254-7176 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 ofAcrolein 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.
