The ELSpe-2 Elemental Speciation Analyzer includes a high-pressure ion chromatography pump, an online speciation digestion system, a post-column hydride generation system (including a gas-liquid separation device), and a chromatography workstation. The detection range of the product covers toys, food, environment, leather, water, and other fields. It enables the elemental speciation analysis of multiple elements, such as As, Hg, Se, Sb, Cr, Br, Sn, Fe, Mn. The As Column and reagent kit are specifically designed for inorganic arsenic analysis. It offers advantages such as good separation efficiency, fast analysis speed, low reagent consumption, low operating costs, and easy operation. It can also perform analysis of methylmercury and ethylmercury.
The system consists of a high-pressure ion chromatography pump, online speciation digestion system, post-column hydride generation system (including a gas-liquid separation device), chromatography workstation, and interface for hyphenation with AFS and ICPMS. It features a complete structure, full functionality, and optimal performance.
The patented hydride generation device saves over 80% of reagent consumption (hydrochloric acid and potassium borohydride).
With an AFS detector, at a concentration of 5 ppb, the signal-to-noise ratio for all components is greater than 30, and the detection limits are below 0.5 ppb for all species.
