The matrix spike is an aliquot of sample <br /> fortified with known quantities of specific compounds and subjected to the entire analytical procedure. If <br /> the recovery of analytes from the matrix spike does not fall within specified control limits due to matrix <br /> interference,the LCS recovery is to be used to validate the batch. <br /> ZI e in <br /> Project Manager **MS=Matrix Spike,MSD=MS Duplicate,RPD=Relative%Difference 9412B64.AAA <2> <br /> 411� <br />
