(MS - MSD) / ((MS + MSD) / 2). <br />MS / MSD spike recoveries and / or %RPD may fall outside of laboratory acceptance criteria due to one or more of the following reasons: a) the sample is inhomogenous AND contains <br />significant concentrations of analyte relative to the amount spiked, or b) the spiked sample's matrix interferes with the spike recovery. <br />N/A = not applicable to this method. <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 analyte content. <br />DHS ELAP Certification 1644 <br />QA/QC Officer <br />Page 7 of 8 <br />
