However, all results were either five times <br /> greater than the CCB concentration or ND relative to the PQL. <br /> 360 CCV above Acceptance Range (AR). Samples which were non detect for this analyte were accepted. <br /> Definitions <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 <br /> recovery. <br /> i MS1M5D 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 /> MDL Method Detection Level <br /> s ICB Initial Calibration Blank - Analyzed to verify the instrument baseline is within criteria. <br /> I 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 /> DQO Data Quality Objective - This is the criteria against which the quality control data is compared, <br /> �r <br /> F,` <br /> STK637202: Quality Control Page 3 <br />
