The Thermo Scientific Model 83i GC Mercury Probe/Converter is one of the four major components of the Mercury Freedom System.
The Model 83i GC Probe/Converter consists of a dilution probe and a proprietary dry converter/scrubber housed in an insulated enclosure. The probe has been specifically designed for monitoring mercury emissions from coal-fired power plants and waste incinerators. Artifacts due to interactions with the fly ash are minimized using a sintered-metal filter to provide a particle-free, vapor-phase sample for analysis. Low-flow reduces deposits from wet stacks. Automated blow-back helps to ensure trouble-free continuous operation, and all components exposed to sample gas are glass-coated stainless steel, Teflon, Hastelloy or glass.
