The PSP103 Gas chromatograph
Implementation of the standards: GB / T 17623-1998 GB / T 7252-2001 DL / T 722-2000
PSP103 type gas chromatograph is the latest development of a new generation of gas chromatograph. The instrument uses a microcomputer automatic control, full keyboard, large screen LCD Chinese display with high precision temperature control, stable and reliable performance, high sensitivity, good repeatability.
Implementation of the standards: GB / T 17623-1998 "component content of dissolved gases in the insulating oil gas chromatographic method
GB / T 7252-2001 "transformer oil dissolved gas analysis and judgment guide
DL / T 722-2000 "transformer oil dissolved gas analysis and judgment Guidelines
The instrument uses a double column parallel shunt system. Equipped with a TCD detector and dual FID detector, as well as the conversion of methane, a single injection Dissolved Gas nine components (H2, O2, N2, CH4, C2H2, C2H4, C2H6, CO, CO2) of the full analysis. Power system can be used for oil and gas equipment internal fault detection, hydrogen-cooled generator cooling medium, and sulfur hexafluoride (SF6) impurity analysis, boiler flue gas analysis, gas analysis and environmental monitoring and analysis. Both exclusive analysis, but also for the general analysis, and thus become the most effective equipment for the petroleum, chemical, mining and other systems for gas analysis.
