#=QL# QUALIFIERS DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to changes in sample preparation, dilution of the sample aliquot, or moisture content. ND - Not Detected at or above adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit. S - Surrogate 1,2-Diphenylhydrazine (8270 listed analyte) decomposes to Azobenzene. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) (D) - Matrix (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. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. LABORATORIES PASI-O Pace Analytical Services - Ormond Beach ANALYTE QUALIFIERS I D4 J(M1) N2 Q The reported value is between the laboratory method detection limit and the laboratory practical quantitation limit. Sample was diluted due to the presence of high levels of target analytes. Estimated Value. Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. The lab does not hold TNI accreditation for this parameter. Sample held beyond the accepted holding time. Page 13 of 16
