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 significant concentrations of analyte relative to the amount spiked,or b)the spiked sample's matrix Interferes with the spike recovery. WA=not enough sample to perform matrix spike and matrix spike duplicate. 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. am DHS ELAP Certification No 1644 QA/QC Officer 1110
