IT has been found that the electrical conductivity of a flame burning a mixture of hydrogen and nitrogen (in air) is very sensitively affected by the vapours of organic substances, and this effect ...

The Flame Ionization Detector (FID) used to measure hydrocarbon content in emission samples uses a hydrogen flame that produces little ionization. Hydrocarbons introduced into this flame produce large ...

The basis of operation of this detector is the increase in the electrical conductivity of a hydrogen flame which occurs when organic compounds are burned in the flame.

This customized Agilent 7890B Gas Chromatography system is equipped with a gas sampling valve at the inlet which is designed for direct gas sample tests. Two detectors, Thermal Conductivity Detector ...
