Model 200 Hydrocarbon Analyzer -
FID Dual Channel, Methane / Non-Methane (NMHC), Oven Heated Total Hydrocarbon Analyzer
The VIG Industries, Inc. Model-200 is a microprocessor based, oven heated methane / non methane / total hydrocarbon gas analyzer designed for high accuracy, sensitivity and stability. The Model-200 uses two independent flame ionization detectors (FID), one to measure total hydrocarbons and the second coupled with a GC (gas chromatography) column for the separation of the methane and non methane components.
A sample is fed to the analyzer via an internal heated pump to the first FID for a continuous real time total hydrocarbon reading. A portion of the sample is trapped and pushed through a GC 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 non methane component.
The detectors, pump head, capillaries, sample filter, all sample lines, GC column, solenoid valves and all other 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.
