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 recover is to be used to validate the batch. <br /> Kay�n• lmyal <br /> Project Manager <br />
