<br /> Control Limits
<br /> Please Note:
<br /> The LCS is a control sample of known,interferent-free matrix that Is analyzed using the same reagents,
<br /> CP ANALYTICAL, #1 624 preparation,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 j
<br /> interference,the LCS recove is to be used to validate the batch.
