METHOD AND THE APPARATUS USED FOR GAS-CHROMATOGRAPHY ANALYSIS OF THE HYDROGEN-CONTAINING GASEOUS MIXTURES Russian patent published in 2007 - IPC G01N30/02 

FIELD: chemical industry; methods and the apparatuses for the gas-chromatography analysis of the hydrogen-containing gaseous mixtures.

SUBSTANCE: the invention is pertaining to the method and the apparatus for the gas-chromatography analysis of the hydrogen-containing gaseous mixtures. The method provides for feeding of the gaseous mixture in parallel into two channels - the channel of H₂ analysis_{and the channel of the rest gases analysis. At that in the channel of H2 analysisadditionally exercise separation and detection of the rest gases and conduct calibration with usage of the method of the internal standard for one of the gases. The apparatus for the gas-chromatography analysis of the hydrogen-containing gaseous mixtures includes two parallel channels - the channel of H2 analysis and the channel of analysis of the rest gases, where each of the channels contains, at least, two sequential separating columns located in the thermostatic oven and is supplied with the detector. In both channels after the first separating column along the running gaseous mixture there is the additionally mounted system with possibility to disconnect the second separating column and to feed the gaseous mixture at once onto the detector. The invention ensures realization of the complete separation of the hydrogen-containing gaseous mixtures with the high accuracy.}

EFFECT: the invention ensures realization of the complete separation of the hydrogen-containing gaseous mixtures with the high accuracy.
