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 enough sample to perform matrix spike and matrix spike duplicate. <br />■ NR = a concentration in sample exneeds spike amount for soil matrix or exceeds 2x spike amount for water matrix or sama diluted due to h' h matrix or ana a content. <br />QA/QC Officer <br />Page 21 of 21 <br />
