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 /> interference,the LCS recoveryis to be used to validate the batch. <br /> Ke eth imer **MS=Matrix Spike, MSD=MS Duplicate, RPD=Relative%Difference <br /> Proj ct Manager <br /> 6041807.CAM <9> <br />
