<br />' Please Note
<br /> The LCS is a control sample of known,interferent tree matrix that is analyzed using tha same reagents,
<br /> UOIA ANALYTICAL, #1271 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 fail within specified control limits due to matrix
<br /> Interference,the LCS recovery13 to be used to validate the batch
