Transformer Oil Dissolved Gas Chromatography Analyzer
Ⅰ: Overview about the Transformer Oil Dissolved Gas Chromatography Analyzer:
Gas chromatography is a technique for separation and analysis of multi-component mixtures. It mainly uses the boiling point, polarity and adsorption coefficient of each component of the sample in the chromatographic column differences, so that each component is separated in the chromatographic column, and the separation of each component for qualitative and quantitative analysis.
The gas chromatograph takes the gas as the mobile phase (carrier gas). When the sample is sent into the sampler and vaporized, it is carried into the packed column or capillary column by the carrier gas. Due to the differences in the boiling point, polarity and adsorption coefficient of each component in the sample, the components are separated in the column. Finally, it is sent to the chromatographic workstation through the network, and the chromatographic workstation records and analyzes the gas chromatogram of each component, so as to obtain the analysis report of each component.
