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 /> recovery of analytes from the matrix spike does not fall within specified control limits due to matrix <br /> interference,the LCS recovery is to be used to validate the batch. <br /> P e <br /> SE <br /> enner <br /> Pro ct anager MS=Matrix Spike,MSD=MS Duplicate, RPD=Relative%Difference 9808957.BLA <4> <br /> _0:�' <br />
