The matrix spike is an aliquot of sample <br /> fortified with known quantifies 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 /> interference,the LCS recovery is to be used to validate the batch. <br /> ie ga ga yy Penner <br /> Difference 950&RB3.BLA <I> <br /> Project Manager MS=Matrix Spike, mSD=MS Duplicate, RPD=Relative% <br />
