The matrix spike is an aliquot of sample <br /> ed 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 fail within specified control limits due to matrix <br /> interference,the LCS recovery is to be used to validate the batch.
