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.
