<br /> Control Limits
<br /> -Please Note:
<br /> The LCS Is a control sample of known,irtterierent-(tee matrix that Is analyzed using the same reagents,
<br /> SEQUOIA 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. ff
<br /> the recovery of analytes from the matrix spike does not tali within specified control limits due to matrix
<br /> \ �Ler
<br /> Interference,the LCS is to be used to validate thebrCeT - tke, - tl�. %
