VIG Model 200/1 FID Methane/Non-Methane (NMHC) Hydrocarbon Analyzer

The VIG Industries, Inc. Model 200/1 is a microprocessor based, oven heated  methane / non methane (NMHC) hydrocarbon analyzer for high accuracy, sensitivity and stability. The Model 200/1 measures methane and non methane hydrocarbons at preset intervals. The VIG Model 200/1 uses one(1) Flame Ionization Detector (FID) to obtain methane and non-methane hydrocarbon readings. A sample is fed to the analyzer via an internal heated pump. After the sample reaches the analyzer, a portion of the sample is trapped and fed through a GC (gas chromatography) column to separate the methane from the total and is fed to the FID detector for analysis. As soon as the methane is read, the remaining sample is back flushed through the GC column and fed to the FID detector for analysis of  the non-methane component. The LCD display indicates the amount of methane and non-methane hydrocarbons.

The Model 200/1 utilizes one flame ionization detector (FID). The detector, all sample lines, GC column and all solenoid valves that come in contact with the sample are maintained in a controlled, heated oven to prevent condensation, and to provide reliable performance in the analysis of concentrations of wide varieties of hydrocarbons in gaseous mixtures and in ambient air.
