Transformer Oil Analysis Dedicated Gas Chromatograph

Instrument Introduction:

The GC-9890BD transformer oil gas chromatograph is a multipurpose gas chromatograph designed in accordance with the power department's standards, widely incorporating the advantages of similar instruments from both domestic and international markets. The instrument features a dual-column parallel分流柱 system, equipped with a thermal conductivity detector, a dual-hydrogen flame detector, and a conversion furnace.

The instrument allows for a comprehensive analysis of dissolved gas components in oil in a single sampling. Primarily applied in the internal fault detection of oil-filled electrical equipment in power systems, the instrument is multi-functional and can be used for analyzing cooling media in hydrogen-cooled generators and flue gas analysis from boilers.And environmental detection and analysis. Additionally, it is widely used in gas analysis for systems such as oil, chemical, and mining industries.
