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.
