Model 8800 NMHC NonMethane Hydrocarbon Analyzer
Baseline - MOCON, Inc.8800 analyzers provide nearly limitless flexibility and offers continuous, fully automated gas analysis over a broad range of concentrations.
With an admirable dynamic range from less than 0.1 ppm to 1,000 ppm, the Model 8800 NMHC is designed to measure the total, methane, and nonmethane hydrocarbon content of gas samples. The analyzer has a generous complement of analog, digital, and logic output capabilities with room to expand. This instrument is well ahead of the competition in performance, automation, and configurability.
The analyzer is based on an electronically flow controlled flame ionization detector (FID) and an oxidation catalyst that is switched in and out of the sample stream. Total hydrocarbons are measured first, and then the oxidizer switches in. The catalyst oxidizes all hydrocarbons except methane, for a methane measurement. The methane value is then automatically subtracted from the total hydrocarbon concentration to determine the non-methane hydrocarbon reading.
The Model 8800 NMHC can be configured with internal components for a single or multipoint analysis of ambient, non-condensing gas samples. The automatic calibration feature enhances the long-term analytical stability of the instrument.
