Control Limits: 55-1306/a <br /> Relative%Difference: 112% <br /> MS/MSD Batch#: TPHDW-1302 <br /> MS%Recovery: See Note <br /> MSD%Recovery: See Note <br /> Relative%Difference: See Note <br /> Note:Insufficient sample material to prepare MS/MSD samples. 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 /> ANALYST: a2VAPPROVIED BY: <br /> Clari J.
