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.
