• Gasmet CVAF (Cold Vapor Atomic Fluorescence) mercury analyzer, which has an integrated high temperature dry thermal converter for converting all mercury compounds to atomic mercury. This analyzer has a detection limit less than one ng/Nm3.
• Gasmet Mercury Calibrator generates calibration gas for automatic zero – and span calibrations, with wide ranger for mercury concentration and gas delivery rate and for atomic mercury Hg0 or mercury chloride HgCl2.
• Gasmet Gasmet Mercury Sampling System includes heated sample gas lines and Gasmet sample dilution probe, heated probe tube and effective blowback system for the filter.

• Very low detection limit with CVAF technique
• No need for separate chemicals, gold amalgamation concentrators, acid scrubbers, or additional gases
• Virtually no interference from other gases such as SO2, HCl
• Direct sampling with sample dilution and effective filter blowback system – simple probe design
• Simple and reliable system with low need for maintenance

GASMET CMMS employs atomic fluorescence spectroscopy and thermal conversion of ionic mercury compounds to atomic mercury. No wet chemistry or gold amalgamation trap is needed. High inherent sensitivity of the atomic fluorescence spectroscopy enables extensive dilution of the sample gas. The diluted sample gas is transported to the analyser. Directly after thermal reduction of the mercury compounds the dry gas containing only atomic mercury is lead to the sample cell. Calibration of the whole system is performed with an automatic calibration unit capable in producing constant flow of both atomic and oxidised mercury. GASMET CMMS Ambient is a modified version of GASMET CMMS for ambient applications with no ionic mercury present in sample gas. In spectrometer the conversion unit is replaced with heated dilution ejector part. In calibrator unit multipoint cold sampling system is constructed instead of equipment for oxidised mercury generation.
