Gas chromatograph for Baijiu

Gas chromatograph: GC-90

Chromatography column: 30m capillary column

Split/non split inlet: inlet temperature of 200 ℃, split ratio of 3:1

Constant current mode: 5ml/min

Carrier gas: high-purity nitrogen

Detector: FID 180 ℃, hydrogen 30ml/min, air 400ml/min, tail blowing+column flow rate 30ml/min

Headspace conditions: equilibrium temperature of 80 ℃, valve and quantitative loop temperature of 90 ℃, transmission line temperature of 100 ℃, equilibrium time of 30 minutes,

Product Technical Parameters:

1. The instrument adopts a fully microcomputer control system, with a large screen LED display in both Chinese and English, providing rich and intuitive display content;

2. New digital design, highly integrated electronic circuit, excellent reliability and anti-interference ability, Chinese keyboard operation, parameter setting and operation

Very convenient.

3. The column box structure is compact, the layout is reasonable, and the temperature is uniform. The intelligent dual channel rear door design makes the cooling speed faster (from 280 ℃ to 50 ℃)

Only takes 8 minutes), with higher efficiency and stable control at room temperature of 5 ℃, expanding the application range of the instrument.

4. The instrument can be equipped with two packed column gasification chambers and one capillary gasification chamber simultaneously, or with two capillary gasification chambers simultaneously, and can be operated by a single amplifier

Expand the amplifier to a dual amplifier. According to different analysis applications, different combinations can be used to install up to three detectors simultaneously, such as FID, TCD, ECD

Detector, etc. Can easily achieve the series and parallel operation of detectors. Truly achieving one machine with multiple uses.

5. The instrument can be equipped with capillary columns of different specifications (caliber 0.2-0.53MM), and its reasonable capillary injection system design (with/without diversion)

The injection, diaphragm blowing, and tail blowing systems make the out of column effect small and the column efficiency high; Create a peak shape with high chromatographic peak height, narrow half peak, and no tailing, thus obtaining

Accurate quantitative results and good reproducibility.

6. The instrument adopts a modular design, making installation simple and maintenance more convenient; The new FID has a lower detection limit and can be conveniently used for nozzle spraying

The disassembly and cleaning of the ion collection electrode, as well as the accurate fixation of the emitter installation structure, ensure a high degree of consistency in the performance of each instrument.

7. The gas circuit adopts a dual design of first stabilizing the voltage and then stabilizing the current; Stable regulation mode, with high precision, high reliability, and convenient and intuitive flow regulation. Having a break

Gas/leakage protection and prompt function, can automatically cut off TCD bridge current, protecting rhenium tungsten wire from injury.

8. Equipped with a six channel temperature control system, including column chamber, gasification chamber, detection chamber, converter, and external control events.

9. It has a nine order linear program heating function, which can meet the analysis of multi-component samples.

10. It has power-off protection, over temperature protection, and power on self-test functions.
