The matrix spike is an aliquot of sample <br /> 0.11 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 /> 1U( " interference,the LCS recovery is to be used to validate the batch. <br /> Vickie Tague <br /> Project Manager 31-30D01MAT <5> <br /> I <br /> i <br />
