Product Description
Introduction
DGA2013-1 power system dedicated insulation oil and gas chromatograph runs by computer automatic control, all-keyboard operation and large-screen liquid crystal display according to the requirements of power system«dissolved gas component determination in insulation oil (chromatography)» ,and is characterized by high-precision temperature control, stable and reliable performance, high sensitivity, good reproducibility and so on.
The analyzer adopts double- pillar parallel shunt system ,equipped with TCD, double FID and methane conversion oven , and c ould achieve total analysis of nine components (H 2 ,O 2 ,N 2 ,CH 4 ,C 2 H 2 ,C 2 H 4 ,C 2 H 6 ,CO, CO 2 )of dissolved gas in insulation oil by one time.
The analyzer can be employ ed for internal fault detection of power system oil and gas equipment, cooling medium analysis of hydrogen-cooled generators, impurity analysis of sulfur hexafluoride, the boiler flue gas analysis, gas analysis and environmental monitoring analysis. Due to its employment not only for special analysis, but also for general analysis, the analyzer becomes the most effective gas analytical instrument in petroleum, chemical engineering, mining and other systems.

2. Features
2. 1 C omputer - keyboard operation
This realize s five heating zone temperature control, detector control, over-temperature protection, "zero" degree protection, air break protection and other functions, so as to protect the chromatographic column and thermal conductivity rhenium tungsten filament most effectively.
2. 2 L arge-screen liquid crystal display
It could display a large amount of information intuitively and clearly.
2. 3 Advanced chromatography process
Based on only one injection and three - detectors analytical process, the analyzer greatly increases detection sensitivity of hydrocarbon gas. Double hydrogen flame setting also reduce s the detection impact caused by the gas content differences.
