Gas Chromatography (4290)

Product Description

GC-4290 series gas chromatography is the best multifunction one in the same kind of analytical instrument in our country at present. It adopts the most advanced microcomputer control system. Its sensitivity and stability is the best, and the qualitative and quantitative analysis is accurate. Three sample injectors, five kinds of detectors and two packed columns, a capillary column can be combined together. The packed column and capillary column are combined at the same column room.

It can be widely used in petrol chemistry, medicine, sanitation, food, environment, police and academy, scientific research graduate school et al.

For example, the intermediates and product test of the petrol chemistry. The analysis of food pesticide residue and medicine solvent. And as the dedicated GC which is applied in Electric power department for the analysis of the volatile oil gas (such as H2, O2, CO, CO2, C2H2, C2H6 ) of the transformer oil. Specially, it can be both used in off-line and on-line of the above-mentioned volatile gas. The analysis results can be got through the dedicated chromatography workstation and Expert system to analysis the fault of the transformer.

GC-4290-GOA is the analytical instrument for testing Gas Dissolved in insulating oils.

Product description: This instrument is mainly used for testing gas dissolved component (Hydrogen, oxygen, nitrogen, methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide and other content analysis. ) in insulating oils of Oil-filled electrical equipment

Model: GC-4290-GOA
The main configuration: GC-4290 gas chromatograph host, TCD detector, dual FID detector, double-column (TDX01, GDX502), methane conversion furnace, automatic six-way valve (optional), 91 #, 92 # event time control procedures and so on. They are the composition of multi-dimensional chromatography system.

Performance characteristics:
(1) Apparatus host has the feature of 91 #, 92 # event time program and is based on high-performance, high stability of GC-4290 gas chromatograph, in order to achieve the automatic valve switching.
(2) The whole apparatus for multi-dimensional chromatography system, using three detectors, double parallel, a complete sampling of dissolved gases in insulating oil component (H2, O2, N2, CH4, C2H4, C2H6, C2H2, CO, CO2) content in the whole analysis, in which H2, O2, N2 are detected by TCD detector, CO, CO2 furnace by the conversion of methane into methane are detected by FID detector, other hydrocarbons are detected directly from FID detector.
(3) Dual-channel chromatography workstation can collect two-way signal detector at the same time
(4)The measuring range of the dissolved gas in.
