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 QC limits and recoveries for MS/MSD's are advisory only and are not used to accept or <br /> reject batch results. <br /> 7 <br /> ANALYST: APPROVED BY: <br /> Clan J.
