<br /> LCS% Recov : 85
<br /> MSIMSD 60-140
<br /> LCS 70-130
<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 /> QU IA ANALYTICAL W6paration,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 N
<br /> the recovery of analytes from the matrix spike does not fall within specified control limits due to matrix
<br /> interferenoe,the LCS recovery is to be used to validate the batch
