JC-2011 gas chromatograph (discontinued)

1、 Product Introduction
Gas chromatograph refers to a chromatographic analysis instrument that uses gas as the mobile phase. Mainly used for analysis and research in industries such as environmental protection, biochemistry, food fermentation, traditional Chinese and Western medicine, petroleum processing, organic chemistry, and hygiene inspection.
2、 Product parameters
Temperature control technical indicators:
1. Temperature control range: room temperature+8 ℃ -420 ℃ Temperature control objects: column box, detector, thermal conductivity cell, sampler
2. Temperature control accuracy: ± 0.1 ℃ within 200 ℃; ± 0.2 ℃ above 200 ℃
3. Program temperature rise: fifth order linear range rise
4. Cheng Sheng rate: 0.1-30 ℃/minute increments of 0.1 ℃
Technical specifications of detector:

1. Chinese large screen LCD display, rich and intuitive display content, convenient parameter setting.
2. Adopting a microcomputer automatic ignition device.
3. Stable and reliable digital zeroing is adopted to avoid baseline instability caused by potentiometer zeroing.
4. It has a five stage program heating function.
5. The intelligent rear door automatic cooling system with frequency conversion function has a fast cooling speed and achieves true near room temperature operation.
6. The tracking heating method used in the column chamber; Avoiding contamination of the detector caused by rapid heating of the column chamber
7. Single column, dual gas path structure, basic configuration is FID or TCD detector.
8. Equipped with a packed column vaporization chamber and an independent capillary dedicated system, it features high-performance capillary split/non split injectors and tail blowing systems, making it easy to install small-diameter capillary columns, large-diameter capillary columns, and various packed columns.
9. It has power failure protection function and can automatically memorize set parameters. It has anti power mutation interference function and stopwatch timing function
10. Equipped with over temperature protection function, the power automatically shuts off and an alarm is triggered when the temperature exceeds the set upper limit. If the temperature of any circuit exceeds the set temperature, it will automatically stop heating; And there are Chinese prompts for the cause of the fault and alarm prompts
11. It has gas cut-off/leakage protection and Chinese prompt function, which can greatly protect TCD tungsten wire and chromatographic column from damage.
12. Equipped with fault self diagnosis function, displaying Chinese fault causes and alarm prompts at any time
