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 /> AK <br /> interference,the LCS recove is to be used to validate the batch. <br /> harlie Westwater = matrix bptKe, MtiU - MS Duplicate, = Helative a Uitterence <br /> roject Manager <br /> 9052113.SSS <5> <br />
