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 recovery is to be used to validate the batch. <br /> regory <br /> 14 roject Manager "*MS=Matrix Spike,MSR=MS Duplicate,RPD=Relative%Difference 9802D55.CCC <1> <br />
