The recoveries are an indication of how that sample <br />matrix affects analyte recovery. <br />MSD : Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyted. The recoveries <br />are an indication of how that sample matrix affects analyte recovery. <br />MSRPD : MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation <br />and analysis. <br />DQO : Data Quality Objective - This is the criteria against which the quality control data is compared. <br />Page 7 of 7
