The matrix spike is an aliquot of sample <br /> �{ #1210, & #224E fortified with known quantities of specific compounds and subjected to the entire analytical procedure. If <br /> 1` 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 /> eFfer <br /> Project Ma <br /> 8121495,GET ¢7> <br />
