<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 /> EQUOIA ANALYTICAL preparation,and analyteal 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 0
<br /> the recovery of analytes from the matrix spike does not fail wrthm specified control Iimrts due to matrix
<br /> U 1 I interference,the LCS recovery is to be used to validate the batch
