Total, methane and non methane Hydrocarbon Analyzer VIG 200-E

Introduction

The VIG Industries Model 200-E is a microprocessor based, oven heated methane / non-methane / total hydrocarbon gas analyzer designed for high accuracy, sensitivity and stability. The Model 200-E 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 non-methane 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 non-methane 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.
