Model 210 Hydrocarbon Analyzer -
FID
Oven Heated Methane / Ethane / Non Methane Ethane (NMEHC)
/ Total Hydrocarbon Analyzer
The VIG Industries, Inc. Model 210 is a microprocessor
based, oven heated methane / ethane
/ non methane-ethane (NMEHC) total hydrocarbon analyzer for high accuracy,
sensitivity and stability. The Model 210 measures methane, ethane, non methane-ethane hydrocarbons at preset
intervals and continuously measures total hydrocarbons in real time. The Model
210 uses two (2)
Flame Ionization Detectors (FID). One FID is used to obtain methane,
ethane and non methane ethane hydrocarbon readings. The second FID is used to
continuously measure total hydrocarbons. A sample is fed to the analyzer via
an
internal heated pump. After the sample reaches the analyzer it is fed to the
first FID to measure total hydrocarbons. A small portion of the sample is trapped and fed through a
GC (gas chromatography) column to separate
the methane and ethane from the total and is fed to the second FID detector for analysis. 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) and total hydrocarbons.
The Model 210 utilizes two flame
ionization detectors (FID). The detectors, 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.
