CCV : Continuing Calibration Verification - Analyzed to verify the instrument calibration is within criteria. CCB : Continuing Calibration Blank - Analyzed to verify the instrument baseline is within criteria. Blank Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples. LCS Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery. Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample MS matrix affects analyte recovery. : Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyte. The recoveries MSD are an indication of how that sample matrix affects analyte recovery. : Blank Spikes - A blank is spiked with a known amount of analyte. It is prepared to verify that the preparation process is not BS affecting analyte recovery. Page 8 of 9
