The matrix spike is an aliquot of sample <br /> fortified with known quantifies 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 recoveryis to be used to validate the batch. <br /> etggy P ner <br /> Project nager <br />
