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 /> an Ki **MS=Matrix Spike,MSD=MS Duplicate,RPO=Relative%Difference <br /> Project anager 9809749.AAA <1> <br />
