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 /> i1 interfefence,the LCS recovery is to be used to validate the batch. <br /> anne Fegley **NIS=Matrix Spike, MSD=IVIS Duplicate, RPD=Relative%Difference <br /> Project Manager <br /> 9010006.GET <8> <br />
