The recoveries are an indication o <br /> how that sample matrix affects analyte recovery. <br /> BS/BSD Blank Spikes - A blank is spiked with a known amount of analyte. It is prepared to verify that the preparation <br /> process is not affecting analyte recovery. <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 /> F, <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 /> FF ND Nan-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 /> F <br /> i <br /> 1 <br /> i <br /> F-il <br /> Fi I <br /> i <br /> F1 S <br /> 1 <br /> R STK731330: Quality Control Page 2 i <br /> I <br /> t <br />
