The matrix spike is an aliquot of sample <br /> fordfied with known quardities of spedfic compounds and subjected to the entire ana tical procedure. if <br /> f nthe recovery of analytes from the matrix spike does not fall�kithin specified control limlb due to matrix <br /> 131 interference,the LCS recovery Is to be used to validate the hatch. <br /> Vickie Tag <br /> Project Manager 3KCMI.WAT <3> <br /> s � <br />
