DQO :Data Quality Objective - This is the criteria against which the quality control data is compared. LCS :Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery. MS :Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample matrix affects analyte recovery. MSD :Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyted. The recoveries are an indication of how that sample matrix affects analyte recovery. MSRPD :MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation and analysis. ND :Non-detect - Result was below the DQO listed for the analyte.
