Data was accepted based on the LCS or CCV recovery. <br /> 435 Sample matrix may be affecting this analyte. Data was accepted based on the LCS or CCV recovery. <br /> Definitions <br /> Blank Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples. <br /> RgBlk Method Reagent Blank - Prepared to correct for any reagent contributions to sample result. <br /> LCS Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte <br /> recovery. <br /> MSlMSD Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication o <br /> how that sample matrix affects analyte recovery. <br /> Dup Duplicate Sample - A random sample with each batch is prepared and analyzed in duplicate. The relative percent <br /> difference is an indication of precision for the preparation and analysis. <br /> ICB Initial Calibration Blank - Analyzed to verify the instrument baseline is within criteria. <br /> ICV Initial Calibration Verification - Analyzed to verify the instrument calibration is within criteria. <br /> CCB Continuing Calibration Blank - Analyzed to verify the instrument baseline is within criteria. <br /> CCV Continuing Calibration Verification - Analyzed to verify the instrument calibration is within criteria. <br /> ND Non-detect - Result was below the DQO listed for the analyte. <br /> <1/4 High Sample Background - Spike concentration was less than one forth of the sample concentration. <br /> DQO Data Quality Objective - This is the criteria against which the quality control data is compared. <br /> STK732332: Quality Control Page 2 <br />
