Jksp-1 gas chromatograph

Main functions and features:
1. The instrument adopts Internet communication technology, which can easily form a LAN; Internet enables remote data transmission, remote control, remote diagnosis, and automatic program upgrade.
2. Fully computerized button operation, 5.7-inch large screen with 13 line LCD Chinese display, human-machine dialogue mode, easy to operate.  
3. The brand new integrated digital electronic circuit has high control accuracy, stable and reliable performance, and a temperature control accuracy of up to 0.1.
4. Unique injection port design solves injection discrimination; The dual column compensation function not only solves the baseline drift caused by program temperature rise, but also reduces the influence of background noise, resulting in lower detection limits.
5. Large column box volume: 300 × 280 × 180 can accommodate two 80m capillary chromatography columns simultaneously.
6. Good insulation effect: When the column box, vaporization, and detection are all at 300 ° C, the hot spots on the outer box and top cover are only 40 ° C, which increases the experimental rate.  
7. Unique vaporization chamber design, making the volume smaller; Accessory replacement: The injection pad, liner, polarizing electrode, collection electrode, and nozzle can all be replaced with one hand; Main body replacement: The packed column, capillary sampler, TCD, and FID detector can be completely disassembled with just one wrench, making maintenance very convenient.
8. The intelligent rear door opening system has stepless variable air flow in and out, shortening the system's stable balance time after program temperature rise/fall.
9. Two types of injection systems can be installed simultaneously: packed column and capillary split/non split injection system (with diaphragm cleaning function); Four identical or different detectors can be installed simultaneously: FID, TCD, ECD, FPD, and NPD detectors. Optional automatic/manual gas six way injection valve injector, headspace injector, thermal analysis injector, cracking furnace injector, methane conversion furnace injector.  
10. It has self diagnostic function upon startup, intuitive display of fault information, power-off storage protection function, keyboard locking function, automatic ignition function, and anti power mutation interference function.
Main technical indicators:
1. Temperature control range: room temperature~450 ℃, increment 1 ℃, accuracy ± 0.1 ℃
2. Program heating: 16 step heating rate 0.1-80 ℃/min
3. Communication interface: Ethernet, IEEE802.3
