'MS I MSD spike recoveries and I 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. E E TPH(btex)=sum of BTEX areas from the FID. #Guttered chromatogram;sample peak coelutes with surrogate peak. I NIA=not applicable or 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 i analyte content.
