Relative Percent <br /> Deviation. <br /> %Recovery=100'(MS-Sample)/(Amount Spiked);RPD=100`(MS- MSD)/((MS+MSD)/2). <br /> MS and/or MSD spike recoveries may not be near 100%or the RPDs near 0%if:a)the sample is inhomogenous AND contains significant concentrations of <br /> analyte relative to the amount spiked,or b)if that specific sample matrix interferes with spike recovery. <br /> N/A=not enough sample to perform matrix spike and matrix spike duplicate. <br /> NR=analyte concentration in sample exceeds spike amount for soil matrix or exceeds 2x spike amount for water matrix or sample diluted due to high matrix or <br /> analyte content. <br /> DHS Certification No. 1644 �QA/QC Officer <br />
