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 /> linterference,the LCS recovery is to be used to validate the batch. <br /> eggy Penner <br /> M;Project anag r MS=Matrix Spike,MSD=MS Duplicate,RPD=Relative%Difference 9611305.BLA 44> <br /> 0a <br /> qX3 <br />
