This could indicate a h igh bias for the sample results. Since there were no detectable analyte responses and the remainder of th run QA is within acceptance range, this batch is approved. , e Sample ID: C101 01112-001 CMS3 10 Sample Matrix Spike Run: ICPMS2-C_101105A 11/05/10 17:56 Antimony 0.629 mg/L 0.050 119 70 130 Arsenic 0.661 mg/L 0.031 46 70 130 S Chromium 0.716 mg/L 0.050 113 70 130 Copper 0.302 mg/L 0.047 60 70 130 S Lead 0.551 mg/L 0.050 75 70 130 Molybdenum 0.643 mg/L 0.10 117 70 130 Silver 0.0410 mg/L 0.019 82 70 130 Thallium 0.623 mg/L 0.10 121 70 130 Uranium 0.624 mg/L 0.0042 122 70 130 Zinc 3.23 mg/L 0.11 70 130 A Sample ID: C10101112-001CMSD 10 Sample Matrix Spike Duplicate Run: ICPMS2-C 101105A 11/05/10 18:03 Antimony 0.590 mg/L 0.050 112 _ 70 130 6.4 20 Arsenic 0.607 mg/L 0.031 36 70 130 8.5 20 S Chromium 0.651 mg/L 0.050 100 70 130 9.4 20 Copper 0.237 mg/L 0.047 47 70 130 24 20 SR Lead 0.496 mg/L 0.050 64 70 130 10 20 S Molybdenum 0.613 mg/L 0.10 111 70 130 4.7 20 Silver 0.0394 mg/L 0.019 79 70 130 4.0 20 Thallium 0.593 mg/L 0.10 115 70 130 5.0 20 Oualifiers: RL - Analyte reporting limit.
