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. N/A=not enough sample to perform matrix spike and matrix spike duplicate. N R=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. #surrogate diluted out of range.
