The matrix spike is an aliquot of sample <br /> fortified with known quantities of specific compounds and subjected to the endre analytical procedure. If <br /> the rocow ry 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 /> Vickie Tague Clark <br /> Project Manager MS=Matrix Spike,MSD-MS Duplicate,RPD=Relative%Difference 9411185.WAT <1> <br />
