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.
The gas is considered as carrier gas. When sample gas is sent to sample injector,it will enter into packed column or capillary column by carrier gas. As the boiling point, polarity and adsorption coefficient of each components of sample gas are different, the components will be separate, then the detector behind will detect each components in sequence according to physicochemical characteristic. At last, the chromatographic analyzer will record and analyze the chromatogram of each components and get the results.
