<br /> • Please Note:
<br /> The LC$is a control sample of known,Interferent free matrix that is analyzed using the same reagents,
<br /> UO ANALYTICAL re aration,and analytical methods employed for the samples. 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.
