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 /> �'ayvanKimyai <br /> Project.Manager **IVIS Matrix Spike, MSD=MS Duplicate,RPD Relative%Difference 9803H14.AAA <2> <br /> r, <br />
