The LCS is a control sample of known,interferent-free matrix that is analyzed using the same reagents, <br /> ,4Elap#127 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 <br /> interference,the LCS recovery is to be used to validate the batch. <br /> y <br /> ger **IVIS=Matrix Spike, MSD=MS Duplicate, RPD=Relative% Difference 9807163.BILA <1> <br />
