Data was accepted based on the LCS recovery. <br /> CCV : Continuing 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 /> Blank : Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples. <br /> LCS : Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery. <br /> MS : Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample <br /> matrix affects analyte recovery. <br /> MSD Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyte. The recoveries <br /> are an indication of how that sample matrix affects analyte recovery. <br /> BS Blank Spikes - A blank is spiked with a known amount of analyte. It is prepared to verify that the preparation process is not <br /> affecting analyte recovery. <br /> BSD Blank Spike Duplicate of BS/BSD pair - A blank duplicate is spiked with a known amount of analyte . It is prepared to verify that <br /> the preparation process is not affecting analyte recovery. <br /> Duplicate Sample - A random sample with each batch is prepared and analyzed in duplicate. The relative percent difference is an <br /> Dup <br /> indication of precision for the preparation and analysis. <br /> MSRPD MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation <br /> and analysis. <br /> BSRPD BS/BSD Relative Percent Difference (RPD) - The BS relative percent difference is an indication of precision for the preparation <br /> and analysis. <br /> ND : Non-detect - Result was below the DQO listed for the analyte. <br /> DQO : Data Quality Objective - This is the criteria against which the quality control data is com ared. <br /> Explanation <br /> 430 Post Digestion Spike (PDS) not within Acceptance Range (AR) because of matrix interferences affecting this analyte. Data was <br /> accepted based on the LCS recovery. <br /> 435 Sam le matrix m2y be affecting this anal te. Data was accepted based on the LCS or CCV recovery. <br /> Page 13 of 28 <br />
