GC900C High Efficiency Gas Chromatography Microcomputer Based And High Performance

Product description:

GC900C series gas chromatograph is a microcomputerized, high-performance, multi-purpose intelligent gas chromatograph designed and produced by our company to meet the requirements of the majority of chromatography users, which can choose a variety of detector combinations to meet the requirements of ordinary laboratory, daily production, routine testing and trace and trace analysis, and is widely used in petroleum, chemical industry, pesticides, environmental protection, epidemic prevention, medicine, electric power, scientific research and education and other fields.

Main performance characteristics:

1. Excellent column box performance, can realize the real sense of near room temperature operation, can carry out five-order
program heating, with column box automatic cooling that is, after opening the door function, fast cooling speed, to achieve rapid
cooling.
2. It has six independent control areas: column box, capillary injector, packed column injector, detector, thermal conductivity
cell, and auxiliary.
3. The instrument is equipped with a capillary special injection port and two packed column injection ports at the same time,
according to the packing column and capillary column two gas path systems, which can meet the current chromatographic analysis
requirements for the selection and analysis of various chromatographic columns.
4. The instrument has a double gas path, three injectors, and double packed column system structure, which can effectively
suppress baseline fluctuation and drift in real time, and is suitable for program temperature analysis.
5. The keyboard sets various control and use parameters (including detector operation parameters), and the machine has functions
such as self-diagnosis, power-off protection, file storage and call, and limit temperature setting. It can accurately display the
temperature control set value, actual value, TCD bridge current, FID amplifier sensitivity, retention and analysis time, etc.
6. A variety of detector combinations can be selected according to the use requirements: FID, TCD, FPD, ECD, NPD, etc.
7. Using LCD display, the display content is rich, intuitive and easy to operate.
8. The selection of domestic and foreign famous brand electrical components and carefully selected, coupled with accurate scale
gas control valves, so that the reliability, stability and high sensitivity of the instrument can be guaranteed.
