The analysis and detection of epichlorohydrin and epichlorohydrin can be quickly and accurately analyzed using a GC-7890 gas chromatograph equipped with a FID detector.

Main performance characteristics:
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. The three gas path structure allows for the simultaneous installation of three chromatography columns, FID and TCD detectors, and facilitates the expansion of ECD FPD, NPD detectors, as well as external control equipment such as gas injectors and converters.
5. 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 multi-purpose use of one machine.
6. It has an eight level program heating function.
7. The intelligent rear door automatic cooling system with frequency conversion function has a fast cooling speed and achieves true near room temperature operation.
8. The column chamber adopts a unique tracking heating method; Avoiding contamination of the detector caused by rapid heating of the column chamber
9. Equipped with two fillers at the same timeThe column filled vaporization chamber and an independent capillary dedicated system are equipped with 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.
10. It has power failure protection function and can automatically memorize set parameters. It has anti power mutation interference function and stopwatch timing function
11. 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, heating will automatically stop; And there are Chinese prompts for the cause of the fault and alarm prompts
12. It has a "0 ℃" protection function. When the temperature display of any channel is always "0 ℃", the heating will automatically stop to prevent the heating element from being damaged due to the constant heating of the chamber And there are Chinese prompts for the cause of the fault and alarm prompts
13. It has gas cutoff protection and Chinese prompt function, which can protect TCD tungsten wire and chromatographic column to a limited extent from damage.
14. Equipped with fault self diagnosis function, displaying Chinese fault causes and alarm prompts at any time
