Mercury Probe / Converter, Model 83i GC

The Model 83i GC Mercury Probe is one of the four major components of the Mercury Freedom System.

The Model 83i GC 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 waster 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 operations, and all components are exposed to sample gas are glass-coated to prevent reactions with mercury.

To prevent sample condensation, all key components (filter, eductor and dilution module) are enclosed in a heated aluminum module. The converter/scrubber converts oxidized forms of mercury to elemental mercury while removing interfering gases from the sample stream. Weighing only 75 pounds (including heated stinger), the probe has been designed for easier maintenance and service. The latched cover is easily removed from the probe allowing quick access to the interior. Inside, the components are so easily accessed that they can be service or removed in a matter of minutes.

Designed to meet the provisions of 40CFR Parts 60 and 75, the Mercury Freedom System provides a complete monitoring solution that measure elemental, ionic, and total mercury in exhaust stacks from both coal-fired boilers and waste incinerators.
