How does the 400A work?

The 400A Flame Ionization Detector (FID) THC analyzer tests for the presence and concentration of HC compounds in a continuous gaseous sample by combining the sample with a fuel gas stream, ionizing the present hydrocarbons through combustion, and then measuring proportional charge produced by the presence of the ionized hydrocarbons in the sample.

What is a FID Analyzer?

A Flame Ionization Detector (FID) analyzer tests for the presence and concentration of select compounds in a gaseous test sample by ionizing the compound of interest with a controlled combustion reaction.

What is THC?

Total Hydrocarbon (THC) is a measurement of the hydrocarbon content (aggregated, not specific to an individual HC compound) concentration in a measured sample.
