Model 20 Hydrocarbon Analyzer -
FID Single Channel, Oven Heated Total Hydrocarbon Analyzer
The VIG Industries, Inc. Model 20 is a microprocessor based, oven heated total hydrocarbon analyzer designed for high accuracy, sensitivity and stability. The Model 20 is designed to continuously measure one point.
The Model 20 utilizes a flame ionization detector (FID). The FID, sample filter, all sample lines, solenoid valves, pump head, capillaries, and other components that come in contact with the sample are maintained in a temperature-controlled heated oven to prevent condensation, and to provide repeatable, reliable performance in the analysis of a wide varieties of hydrocarbon concentrations in gaseous mixtures or in ambient air.
