DEVICE FOR GC analysis concentrations of carbon monoxide and methane in multicomponent mixtures

摘要

The invention relates to analytical chemistry, in particular to a gas chromatography, and can be used in the laboratories of chemical plants, research laboratories, analysis of environmental pollution, petroleum products and so forth. In an apparatus for gas chromatographic analysis of carbon dioxide concentration and methane multicomponent mixtures comprising series-connected feeder for the injection, the chromatographic column filled with the stationary phase and the detector, according to useful mode if, before dosing the injection series along the carrier gas motion mounted stabilizer of carrier gas pressure, pressure gauge, variable inductors in parallel with each other and three-way cock, and the chromatographic column is further installed threeway cock and the detection unit comprising a measuring and comparative camera. The stationary phase of the chromatographic column comprises a granular activated with a grain size of 0.3-0.5 mm. In this chromatographic column formed 1200-1300 mm in length with a diameter of 2.95-3.05 mm. The measuring chamber is installed with a thermal conductivity detector operating current of 100-101 mA. As a carrier gas hydrogen is used under pressure 0,24-0,25 kg / cm ³ at a flow rate 2-2.1 L / h.
