The recoveries are an indication of how that sample MS matrix affects analyte recovery. <br />: MSD Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyte. 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 />ND : Non-detect - Result was below the DQO listed for the analyte. <br />DO() : Data Quality Objective - This is the criteria against which the quality control data is compared. <br />Page 7 of 10 <br />Corporate Offices & Laboratory <br />853 Corporation Street <br />Santa Paula, CA 93060 <br />TEL: (805)392-2000 <br />Env FAX: (805)525-4172 / Ag FAX: (805)392-2063 <br />CA ELAP Certification No. 1573 <br />Office 8.
