MS I MSD spike mcovedes 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 signitcent concentrations of analyte relative to the amount spiked,or b)the spiked sample's matrix Interteree with the spike recovery. WA=not enough sample to pedonn matrix spike and matrix spike duplicate. NR=analyte concentration in sample exceeds spike amount for end matrix or exceeds 2x spike amount for water matrix or sample diluted due to high matrix or analyte content. N surrogate diluted out of range or coclutas with another peak;g)Ito surrogate due to matrix Interference. Laboratory extraction solvents such as mathylene chloride and acetone may occasionally appear in the method Wank at low levels. DHS ELAP Certification 1644 QA/QC Officer
