GC 5890N gas chromatograph is a new generation of laboratory gas chromatograph that uses international professional technology, integrates the advantages of domestic (CN) instruments, carries out technological innovation on products, and comprehensively upgrades and launches. A variety of Detectors and packed columns, split/splitless capillary column injection systems are optional; Fully compatible with the Agilent 6890N GC Detector and associated Detector control boards, chromatography workstations, and autosamplers. The cost performance is very good, the performance is excellent, and the operation is stable and reliable.
1. High-precision, multi-functional, connected to international professional technology
The new integrated digital electronic circuit has high control accuracy, stable and reliable performance, and can reach a temperature control accuracy of 0.01°C.
It has the function of self-diagnosis at start-up, the function of stopwatch (convenient for flow measurement), the function of running timer, the function of power failure storage protection, the function of keypad locking, the function of anti-power mutation interference, the function of networked data communication and remote control.
2. The unique design of the sampling system can obtain a lower detection limit
Unique inlet design solves injection discrimination; The double-column compensation function not only solves the program drift caused by the temperature rise, but also subtracts the effect of background noise to obtain a lower minimum detection limit.
There are packed columns, capillary split/splitless injection systems (with diaphragm cleaning).
Automatic/manual gas six-way injector injector, headspace injector, thermal analysis injector, pyrolysis furnace injector, methane reformer, autosampler are optional.
3. The program temperature is raised, the furnace temperature is precisely controlled, and the stable balance is faster
The column box has a large volume, and the intelligent rear door opening system has stepless variable air inlet and outlet volume, which shortens the stable equilibrium time of each Detector system after program lifting/cooling; Heating furnace system: ambient temperature +5°C~420°C; 7-stage programmed heating, heating rate 0.1~120°C/min; The furnace temperature can be recalibrated by the user, and the maximum temperature can be set within 420°C, and the temperature equilibration time of the furnace can be determined by the user.
4. High sensitivity and high stability Detector to meet the needs of different schemes
Six Detectors can be installed: Hydrogen Flame Ionization Detector (FID), Thermal Conductivity Cell Detector (TCD), Electron Capture Detector (ECD), Flame Photometric Detector (FPD), Nitrogen and Phosphorus Detector (NPD), and Photoionization Detector (PDHID).
Each Detector can be independently controlled, and the hydrogen flame Detector is easy to remove and install, making it easy to clean or replace the nozzle.
Thermal Conductivity Cell Detector (TCD) Stability Time: ≦10min.
Forensic science: testing of volatile poisons such as alcohols, aldehydes, and ketones in blood and urine.
Traffic safety: the test of the blood alcohol content of the vehicle driver when drinking alcohol and driving while intoxicated.
Brewing industry: Determination of low boiling point aroma components in beer.
Food industry: Detection of solvent residues in leaching oils.
Environmental protection: such as the determination of volatile halogenated hydrocarbons in surface water and tap water such as rivers, rivers and lakes.
Industry: Detection of residual solvents in *products.
Material control: Detection of acetaldehyde residues in beverage bottles.
