This could indicate a high bias for the sample results. Since there were no detectable analyte responses. and the remainde <br />of the run QA is within acceptance range. this batch is approved. <br />Sample ID: C10120838.001 BMS3 2 Sample Matrix Spike Run: ICPMS2-C-1 101 17A 01/17/11 17:24 <br />Antimony 0.56 mg/L 0.0010 111 70 130 <br />Zinc 0.49 mg/L 0.010 97 70 130 <br />Sample ID: C1 0120838-001 BMSD 2 Sample Matrix Spike Duplicate Run: ICPMS2-C_110117A 01/17/11 17:30 <br />Antimony 0.57 mg/L 0.0010 115 70 130 3.0 20 <br />Zinc 0.49 mg/L 0.010 98 70 130 0.9 20 <br />Qualifiers: <br />RL - Analyte reporting limit. <br />MDC - Minimum detectable concentration <br />ND - Not detected at the reporting limit. <br />S - Spike recovery outside of advisory limits. <br />Page 12 of 25
