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 <br /> recoveries 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 /> Corporate Offices&Laboratory Office&Laboratory Office&Laboratory Field Office <br /> P.O.Box 272/853 Corporation Street 2500 Stagecoach Road 563 E.Lindo Avenue Visalia,California <br /> Santa Paula.CA 93061-0272 Stockton,CA 95215 Chico,CA 95926 TEL 559!734-9473 <br /> TEL:805/392-2000 TEL:209/942-0182 TEL:530/343-5818 Mobile 559/737-2399 <br /> FAX:805/525-4172 FAX:209/942-0423 FAX:530/343-3807 FAX.559/734-8435 <br /> CA NELAP Certification No.01110CA CA ELAP Certification No. 1563 CA ELAP Certification No.2670 <br />
