LCS samples prepared in duplicate. <br /> The LCS(Laboratory Check Sample)is a control sample of known,interferent free matrix that is fortified with representative analytes and <br /> analyzed using the same reagents,preparation and analytical methods employed for the samples. The LCS%recovery is used for validation <br /> of sample batch results. Due to matrix effects,the OC limits and recoveries for MS/MSD's are advisory only and are not used to accept or <br /> reject batch results. <br /> ' ANALYST: PROVED BY: <br /> Clan J.
