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 /> r `l interference,the LGS recovery is to be used to validate the batch. <br /> Vickie Tague Clark <br /> Project Manager MS=Matrix Spike, MSD=MS Duplicate,RPD=Relative%Difference 9506205.CAN <2> <br />
