Introduction GC9790 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 examination bility 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 timesHigh 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. Technical parameters Temperature control range:oven RT+6°C~400°C,( 1°Cincrement) FID,TCD,Injector,Reburner RT+8°C~400°C Accuracy of control temperature:TCD±0.02°C Oven,FID,Injector,Reburner±0.1°C FID limit of detection:≤2×10-12g/s[N-C16] TCD sensitivity:≥8000mV.ml/mg[N-C16] Minimum detectable concentration:H2≤2ppm CO,CO2≤2ppm C2H2≤0.1ppm Data processing system Power system special purpose Gas Chromatography workstation:WIN9X/XP operating environment, entire Chinese contact surface and operation prompt, automatic computation oil gas content. Breakdown automatic diagnosis: Provides conforms to transformer oil the dissolved gas analysis guide GB/T7252-2001 three specific value diagnosis reported , prompts the out of limits result automatically, supports TD graphical representation,component density graphical representation etc pattern. GLP data management: Supports Access database, convenience management,retrieval chromatograph data and other related information. Basic Parameter Dimension: 555*490*480[mm] (L×H×W) Weight:45Kg Max. Power:2500W Power: AC 220V±22V 50HZ±0.5HZ
