Product Description

GC-9890 Portable Transformer oil Chromatograph

Applications:

The process design of GC-9890 transformer oil chromatography analyzer is fully in accordance with the standards of China GB / T7252-2001 Guidelines for Analysis and Judgment of Dissolved Gas in Transformer Oil, GB / T17623-2017 Gas Chromatography of Gas Content in Insulating Oil and the Ministry of Power DL / T722-2000 Guidelines for Analysis and Judgment of Dissolved Gas in Transformer Oil. The machine is equipped with high sensitivity of thermal conductivity detector and hydrogen flame ionization detector, and a nickel catalyst converter, can realize the transformer oil dissolved 7 kinds (or 9) of gas components: hydrogen, (oxygen, nitrogen), carbon monoxide, carbon dioxide, methane, ethylene, ethane, acetylene. Its performance meets the requirements of the gas chromatograph in the above standards.
GB / T7252-2001 Guidelines for Analysis and Judgment of Dissolved Gas in Transformer Oil, GB / T17632-1998 Gas Chromatographic Measurement of Gas Content in Insulation Oil, DL / T722-2000 Guidelines for Analysis and Judgment of Dissolved Gas in Transformer Oil.
GC-9890 transformer oil chromatography analyzer is equipped with TCD detector and FID detector, where H2, O2 and N2 are detected by TCD; CO, CO2, CH4, C2H4, C2H6 and C2H2 are detected by FID
