Abstract
The invention provides a gas chromatography method for analyzing materials vaporizable in a gas chromatograph system, the method including filling a sample injection device with a sample of the compounds to be analyzed; transferring the sample compounds into an analytical separation column with a transfer gas; passing a carrier gas inside the analytical separation column for time separation of the sample compounds; controlling the temperature of the column for achieving separation of the sample compounds; transferring the vaporized sample compounds eluted from the column into a flame ionization detector; providing the gases required for the operation of the flame ionization detector, and analyzing the data output of the flame ionization detector for analysis of the sample compounds, wherein the gases required for the operation of the gas chromatograph system are produced by water electrolysis. In a modification of the method, the gases required for operation of the gas chromatograph system are produced by water electrolysis without separating the hydrogen from the co-produced oxygen. Gas chromatograph systems for analyzing vaporizable materials are also provided.
