Model 210/1 Hydrocarbon Analyzer -
FID Oven Heated Methane / Ethane / Non Methane Ethane (
NME) Gas Analyzer

Model 210 Hydrocarbon Analyzer

The VIG Industries, Inc. Model 210/1 is a microprocessor based, oven heated  methane / ethane /  non methane-ethane (NME) gas analyzer for high accuracy, sensitivity and stability. The Model 210 measures methane, ethane, non methane-ethane hydrocarbons at preset intervals. The Model 210/1 uses 1 Flame Ionization Detector (FID) to obtain methane, ethane and non methane ethane hydrocarbon readings.  A small portion of the sample is trapped and fed through a GC (gas chromatography) column to separate the methane and ethane. As soon as the methane and ethane components are read, the remaining sample is back flushed through the column and fed to the FID detector for analysis of  the non methane ethane component. The LCD display indicates the amount of methane, ethane, residual (non methane ethane).

The Model 210/1 utilizes 1 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.
