A method for the highly accurate quantification of gas streams by on-line chromatography.

Quantification of the gas streams from chemical systems such as catalytic reactors are routinely performed by on-line gas chromatography. Gas chromatographs used for this purpose are typically provided with a combination of thermal conductivity (TCD) and flame ionization (FID) detectors to be able to detect and quantify both permanent gases; CO, N, H, etc., and hydrocarbons.
