GC-9790SE Best Selling Transformer/insulating oil gas chromatograph
Brief introduction GC9790SD gas chromatograph is for the electric power profession design new generation electrical power
system special-purpose gas chromatograph, uses the most advanced crisis control system and the large screen Chinese
display interface, adopt national standard GB/T17623-1998 «In insulating oil dissolved gas component content gas chromatography measuring method »,
GB/T7252-2001 « In the transformer oil dissolved gas analysis and the judgment guide » recommends three detector flows, advanced TCD enlargement technology made to the hydrogen examinatio
ability to enhance 10 times,
high sensitive micro current amplifier caused to the hydrocarbon compound gas examination ability to climb
to the limit, outstanding chromatographic column system assurance good chromatograph peak shape and
the best of high dissociation, stable air circuit control system had guaranteed the analysis accuracy and
repeatability, GC9790SD gas chromatograph is the electric power profession user's best choice.
Advanced TCD enlargement technology, causes to the hydrogen examination ability is common
instrumentation's 10 times
High sensitive micro electric current enlargement technology, causes to the hydrocarbon compound gas
examination limit ability to climb to the limit
Unique back pressure system design, reduces the examination system's fluctuation enormously, raises
the analysis level
Uses three detector flows, two column parallel connection, once injection then realizes 8 kind of gas
component automated analysis
Advanced FLASH memory system, causes the data protection no longer to stalemate in battery's expiration
High sensitive PC control system, realizes the online monitoring perfectly
Classical liquid crystal large screen design, parameter setting is simpler intuitively
Perfect self-diagnosis function, breakdown retrieval is no longer complex
Reliable jamproof system, excessively temperature protection function
Analysis and Application
After sample pours into the vaporizer, diverges to two chromatographic columns,
column 1:GDX-502, Uses to separate the hydrocarbon compound component, obtains the examination on FID1;
column 2:TDX01,uses to separate H2,CO,CO2,first go through TCD examination H2 component, comes out
after TCD and go through reburner CO, CO2 transforms CH4, finally obtains the examination on FID2.
