The matrix spike is an aliquot of sample <br /> & 01210 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 /> � lianne Fegley <br /> Project Manager <br /> 9010010,GET <23> <br />
