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 />8061355.GET <8> <br />
