The GC900C series gas chromatograph is a microcomputer based, high-performance, and multi-purpose intelligent gas chromatograph designed and produced by our company to meet the requirements of a wide range of chromatographic users. Multiple detector combinations can be selected according to needs to meet the requirements of ordinary laboratories, daily production, conventional detection, as well as micro and trace analysis. It is widely used in various fields such as petroleum, chemical industry, pesticides, environmental protection, epidemic prevention, medicine, electricity, scientific research, and education.
Main performance characteristics:
1. Excellent column box performance, capable of achieving true near room temperature operation, capable of five step programmed heating, with automatic cooling of the column box and rear door opening function, fast cooling speed, and fast cooling.
2. It has six independent control areas: column box, capillary injector, packed column injector, detector, thermal conductivity cell, and auxiliary device.
3. The instrument is equipped with a dedicated capillary injection port and two filling column injection ports, which can simultaneously install two gas path systems: filling column and capillary column. It can meet the current requirements for the selection and analysis of various chromatographic columns in chromatographic analysis.
4. The instrument has a dual gas path, three samplers, and a dual packed column system structure, which can effectively suppress baseline fluctuations and drift in real time and is suitable for programmed temperature analysis.
5. The keyboard sets various control and usage parameters (including detector operation parameters), and the machine has functions such as self diagnosis, power-off protection, file storage and retrieval, and limit temperature setting. It can accurately display various temperature control settings, actual values, TCD bridge currents, FID amplifier sensitivity, retention and analysis time, etc.
6. Multiple detector combinations can be selected according to usage requirements, such as FID, TCD, FPD, ECD, NPD, etc.
7. Using an LCD display, the display content is rich, intuitive, and easy to operate.
8. Select domestic and foreign famous brand electrical components and carefully select them, combined with precise scale type pneumatic control valves, to ensure the reliability, stability, and high sensitivity of the instrument.
