The <br /> associated method blank surrogate spike compound was in control and, therefore, the <br /> sample data was reported without further clarification. <br /> 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of <br /> control due to matrix interference. The associated LCS and/or LCSD was in control and, <br /> therefore, the sample data was reported without further clarification. <br /> 4 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 /> 5 The PDS/PDSD associated with this batch of samples was out of control due to a matrix <br /> interference effect. The associated batch LCS/LCSD was in control and, hence, the <br /> associated sample data was reported with no further corrective action required. <br /> A Result is the average of all dilutions, as defined by the method. <br /> B Analyte was present in the associated method blank. <br /> C Analyte presence was not confirmed on primary column. <br /> E Concentration exceeds the calibration range. <br /> H Sample received and/or analyzed past the recommended holding time. <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 /> ME LCS Recovery Percentage is within LCS ME Control Limit range. <br /> N Nontarget Analyte. <br /> ND Parameter not detected at the indicated reporting limit. <br /> Q 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 /> U Undetected at the laboratory method detection limit. <br /> X % Recovery and/or RPD out-of-range. <br /> Z Analyte presence was not confirmed by second column or GC/MS analysis. <br /> 7440 Lincoln Way, Garden Grove, CA 92841-1427 • TEL:(714)895-5494 • FAX: (714)894-7501 <br />
