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 analyte.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. DQO :Data Quality Objective-This is the criteria against which the quality control data is com med.
