The matrix spike is an aliquot of sample <br />fortified with known quantities of specific compounds and subjected to the entire analytical procedure. ff <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 />.a <br />940a514.wAT <4> <br />
