Operator’s Manual Chapter 1: Introduction System Performance Characteristics ‣ Ultra-trace detection limits: < 0.5 ppt at 40 mL / min. carrier gas flow 1 . (Direct steady state absorbance mode, without pre-concentration by gold amalgamation). ‣ Wide dynamic linear working range, ≅ 4 orders of magnitude. ‣ Short term precision (%RSD @ 95% Confidence) < 6.0% @ 5 ppt, n=5 ‣ Short term precision (%RSD @ 95% Confidence) < 1.2% @ 20 ppt, n=5 ‣ Long term precision (%RSD @ 95% Confidence) < 2.7%/h @ 200.0 ppt ‣ 99% Confidence Accuracy @ 5 ppt; ±3.1% ‣ 99% Confidence Accuracy @ 20 ppt; ±4.3% ‣ Sample Throughput < 3.5 min/sample at IDL ‣ Ultra-low drift rates ≤ 300 µAbs/hr (after warm-up) raw uncorrected analog baseline on-screen drifts. ‣ Ultra-low short-term absorbance noise ≤ 200 µAbs (10 -5 Abs). ‣ 0.1% “raw” Hg lamp stability (single beam output). ‣ Unusually fast washout ≈ 240 sec. from 1ppm Hg, at 1000 mL/min gas flow. ‣ Mercury Response: ≥ 14,000 µAbs / ppb 2 at 100 mL/min carrier gas flow. 1 One hour minimum warm-up using the standard Nafion ® dryer and a gas flow equal to 40 mL/min along with prescribed tubing and reagents. Using pump speed, uptake and rinse times specified for standard Nafion ® dryer in Table 4-1 (p. 72), and ≥12 s integration cycle selected on the "flattest" portion of the peak time profile. 2 Using prescribed tubing, reagents, and pump speed. 10
