Glossary of Terms and Qualifiers <br /> jL aboratories, Inc. r <br /> Work Order Number: 12-03-1242 <br /> Qualifier Definition <br /> AZ Surrogate compound recovery was out of control due to matrix interference. The <br /> associated method blank surrogate spike compound was in control and, therefore, the <br /> sample data was reported without further clarification. <br /> B Analyte was present in the associated method blank. <br /> BA The MS/MSD RPD was out of control due to matrix interference. The LCS/LCSD RPD <br /> was in control and, therefore, the sample data was reported without further clarification. <br /> BB Spike recovery and RPD control limits do not apply resulting from the parameter <br /> concentration in the sample exceeding the spike concentration by a factor of four or <br /> greater. <br /> BU Sample analyzed after holding time expired. <br /> DF Reporting limits elevated due to matrix interferences. <br /> E Concentration exceeds the calibration range. <br /> ET Sample was extracted past end of recommended max. holding time. <br /> GE The PDS/PDSD or PES/PESD associated with this batch of samples was out of control <br /> due to a matrix interference effect. The associated batch LCS/LCSD was in control and, <br /> hence, the associated sample data was reported without further clarification. <br /> HD Chromat. profile inconsistent with pattern(s)of ref. fuel stnds. <br /> HO High concentration matrix spike recovery out of limits <br /> HT Analytical value calculated using results from associated tests. <br /> HX Recovery of the Matrix Spike (MS)or Matrix Spike Duplicate (MSD)compound was out <br /> of control due to matrix interference. The associated LCS and/or LCSD was in control <br /> and, therefore, the sample data was reported without further clarification. <br /> IL Relative percent difference out of control. <br /> J Analyte was detected at a concentration below the reporting limit and above the <br /> laboratory method detection limit. Reported value is estimated. <br /> LD Analyte presence was not confirmed by second column or GC/MS analysis. <br /> LP The LCS and/or LCSD recoveries for this analyte were above the upper control limit. The <br /> associated sample was non-detected. Therefore, the sample data was reported without <br /> further clarification. <br /> LQ LCS recovery above method control limits. <br /> LR LCS recovery below method control limits. <br /> ND Parameter not detected at the indicated reporting limit. <br /> QO Compound did not meet method-described identification guidelines. Identification was <br /> based on additional GC/MS characteristics. <br /> RU LCS/LCSD Recovery Percentage is within Marginal Exceedance (ME) Control Limit <br /> range. <br /> SG A silica gel cleanup procedure was performed. <br /> SN See applicable analysis comment. <br /> U Undetected at detection limit. <br /> Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not <br /> corrected for% moisture.All QC results are reported on a wet weight basis. <br /> MPN - Most Probable Number <br /> 7440 Lincoln Way, Garden Grove, CA 92841-1427 9 TEL:(714) 895-5494 • FAX: (714)894-7501 <br />
