Heated Methane / NonMethane / Total Hydrocarbon Analyzer (NMHC) Model-200 The VIG Industries, Inc. Model-200 is a microprocessor based, oven heated methane / nonmethane / total hydrocarbon gas analyzer designed for high accuracy, sensitivity and stability. The Model-200 uses two independent flame ionization detectors (FIDs), one to measure total hydrocarbons and the second coupled with a GC Column for the separation of the methane and nonmethane components. A sample is fed to the analyzer via an internal heated pump to the first FID for a real time total hydrocarbon reading. A portion of the sample is trapped and pushed through a column to separate the methane component and then to the second FID. Any remaining sample in the column is back flushed through the column to obtain the nonmethane component. All components that come in contact with the sample through analysis are maintained in a temperature-controlled oven to prevent condensation, and to provide repeatable, reliable performance in the analysis of a wide variety of hydrocarbon concentrations in gaseous mixtures or in ambient air. • Easy to use software • Automatic start-up/ignition • Heated sample pump heads • Two stage sample filter with exchangeable sintered stainless steel elements • PTFE isolated detectors (FIDs) • Automatic fuel shut-o system • Automatic flame-out indicators • Adjustable alarm and oven settings • Precision 1% of full scale • 4-20mA output - no extra charge • Zero and calibration solenoids with software • RS-232 interface • Internal combustion air supply Related Available Equipment • • • • • Zero air generator (Reduces bottles) Hydrogen generator (Reduces bottles) Heated sample lines and controllers Strip chart recorders and data loggers NEMA rated enclosures • Compliance Monitoring - U.S. E.P.A.
