Mercury Analayzers At A Glance OVERVIEW Hydra IIAA Principle Analytical Chemical reduction Technique followed by cold vapor atomic absorption (CVAA) Chemical reduction followed by cold vapor atomic absorption (CVAA) Chemical reduction with or without Hg pre-concentration followed by cold vapor atomic fluorescence (CVAF) Thermal decomposition followed by amalgamation and atomic absorption Sample Matrix • Aqueous samples • Aqueous samples • Hg measured from • Hg measured from low ng/L to mg/L levels sub ng/L to high µg/L levels • Aqueous samples • When the lowest detection levels are required • Solid, semi-solid matrices • Analysis without sample preparation Instrument Detection Limit Short Term Precision (% RSD @ 95% Confidence, N=5) Usable Range 0.5 ng – 1500 ng; <25,000 ng with extended range option
