Headspace injection gas chromatograph

Automatic headspace injection chromatograph GC-9860DApplicable for: detection of alcohol in blood; Detection of solvent residues in food packaging; Testing of color printing inks and adhesives for food packaging; Detection of residual solvents in cigarette filter paper; Residual detection of ethylene oxide in medical devices, etc!

Main performance characteristics:
1. The instrument adopts a fully microcomputer automatic control system, an adjustable LCD display screen, and rich and intuitive display content; Chinese keyboard style operation, setting parameters and operation are very convenient.
2. Adopting a brand new dual CPU design and original Japanese high integration electronic circuit technology, it has excellent reliability and anti-interference ability. The temperature control accuracy reaches 0.1 ℃, and the display accuracy is as high as 0.01 ℃. It can also display the power consumption percentage of each heating part at the same time.
3. The design of a three gas path and a large volume column chamber allows for the simultaneous installation of three chromatography columns, FID and TCD detectors, and facilitates the expansion of ECD, FPD, and NPD detectors, as well as the installation of external control equipment such as gas injectors and converters.
4. This machine can be easily expanded from a single FID amplifier to a dual FID amplifier, achieving multiple uses on one machine.
5. Equipped with two packed column vaporization chambers and an independent capillary dedicated system, the design of the vaporization chamber draws on the miniaturization design of similar foreign products, with fast heating speed, no injection dead corners, excellent capillary diversion/non diversion injector and tail blowing system, making it easy to install small-diameter capillary columns, large-diameter capillary columns, and various packed columns.
6. It has a five order linear program heating function, which is suitable for multi-component sample analysis.
7. The column chamber is equipped with a frequency conversion intelligent rear door automatic cooling system, which has a very fast cooling speed (reducing from 280 ℃ to 50 ℃ in just 5 minutes), achieving near room temperature operation in the * * sense.
8. Equipped with six independent temperature control systems Suitable for the installation of multiple temperature control requirements such as conversion furnaces; The column chamber, gasification chamber, hydrogen flame detection chamber, thermal conductivity detection chamber, auxiliary 1, and auxiliary 2 all adopt modular design, making installation and replacement more convenient.
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, heating will automatically stop; And there are prompts for the cause of the malfunction and alarm prompts.

11. 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 prompts for the cause of the fault and alarm prompts
12. The gas cut-off protection and prompt function in similar products can provide limited protection for TCD tungsten wires and chromatographic columns from damage.
13. It has a wide range of fault self diagnosis functions, 36 types of self diagnosis information, and can display the cause and handling methods of faults at any time.
14. Stable pneumatic system:
(1) The carrier gas flow rate adopts a dual stability design of first stabilizing the pressure and then stabilizing the current;
(2) The pneumatic control valve components have high reproducibility and stability.
15. Multiple injection methods are available:
(1) Fill the column head for injection;
(2) Filling column gasification injection;
(3) Capillary diversion/non diversion injection: back pressure valve control technology, linear diversion;
(4) Six way valve gas injection;

(5) Automatic headspace injection;
