GDC-9560B Gas Chromatograph Analyzer is to analyze the gas content of insulation oil by gas chromatographic method. It is effective to judge if the running equipment has potential fault like over-heat, discharge or not, to ensure the safety of power grid. It is also necessary to be used for manufacturer of gas/oil equipment to inspect their equipment before leaving factory.
Gas chromatography analysis technology is a technique for separation and analysis of multi-component mixtures. It mainly uses the difference of boiling point, polarity and adsorption coefficient of each component in the sample in the column, so that the components are separated in the column, and the separated components are qualitatively and quantitatively analyzed.
The gas chromatograph uses a gas as the mobile phase (carrier gas). When the sample is sent to the injector and vaporized, it is carried by the carrier gas into the packed column or capillary column due to the boiling point, polarity and adsorption coefficient of each component in the sample. The difference is that the components are separated in the column, and then the detectors connected to the column are sequentially detected according to the physicochemical characteristics of the components, and finally the converted electrical signals are sent to the chromatographic workstation. The gas chromatogram of each component is recorded and analyzed by a chromatographic workstation to obtain analysis results of each component.
