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. £TPH(btex)=sum of BTEX areas from the FID. #cluttered chromatogram;sample peak coelutes with surrogate peak. N/A=not enough sample to perform matrix spike and matrix spike duplicate. NR=matrix interference and/or 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 CDPH ELAP 1644♦NELAP 12283CA QA/QC Officer Page 12 of 14
