Main performance characteristics:
1. Chinese large screen LCD display, with rich and intuitive display content, and 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 an eighth order program heating function.
5. The intelligent rear door automatic cooling system with frequency conversion function has a fast cooling speed, achieving true near room temperature operation.
6. The column chamber adopts a unique tracking heating method; Avoiding contamination of the detector caused by rapid heating of the column chamber
7. The three gas path structure allows for the simultaneous installation of three chromatography columns, both FID and TCD detectors, and facilitates the expansion of ECD, FPD, NPD detectors, as well as the installation of external control equipment such as gas injectors and conversion furnaces.
8. Equipped with an independent capillary dedicated system, two packed column injection systems, and a high-performance capillary split/non split injector and tail blowing system, it can easily install small caliber capillary columns, large caliber capillary columns, and various packed columns.
9. This machine can be easily expanded from a single FID amplifier to a dual FID amplifier, and the parameters of the two amplifiers can be controlled separately, truly achieving one machine with multiple uses.
10. It has a power-off protection function and can automatically memorize set parameters. Equipped with anti power mutation interference function and stopwatch timing function
11. Equipped with over temperature protection function, automatically power-off and alarm when the temperature exceeds the set upper limit. If the temperature of any path exceeds the set temperature, it will automatically
Stop heating; And there are Chinese prompts for the cause of the malfunction and alarm prompts
12. Equipped with gas cut-off/leakage protection and Chinese prompt function, it can maximize the protection of TCD tungsten wire and chromatographic column from damage.
13.Equipped with self diagnosis function for faults, displaying Chinese fault causes and alarm prompts at any time
