GC-4000A Gas Chromatograph 


Product Description


1. Application


It can choose to install hydrogen flame detector, flame photometric detector, electron capture, and thermal detector. According to the national standard for medicine, pesticide, food (meat, cooking oil, vinegar, soy sauce, wine, rice, flour, candy, cakes, tea, drinks, etc.) and food packaging containers, agricultural products (vegetables, fruits, etc.), water and wading products, cosmetics, biological materials, environmental soil, animal feed and the low boiling point of organic compounds in the samples detection, this type of instrument can perform the quantitative analysis and confirmed analysis determination. If added some appropriate accessories, it can also detect all kinds of the building materials chemical raw materials, other agricultural and sideline products, and all kinds of articles for daily use of harmful residues for testing.

As for some objects mentioned above, it can used to detect adulteration.


2. Features


1. Flexible and reasonable instrument design allows that it can be equipped with hydrogen flame ionization detector, electron capture detector and flame photometric detector, which has three independent gas paths, circuit systems, and three signal output terminal. This design is greatly convenient the users to use, avoiding the replacement of detector operation, and reducing the fault rate.

2. It has unique design and stable temperature control system, which has eight temperature control points, and two points can be carried out eight steps control; Sampler and the detectors can be individually climate-controlled, and have the function of over-temperature protection.

3. It has flexible packed column and capillary column system, apparatus is equipped with two syringe injection ports and shunt/no bypass capillary devices.

4. Mass oven, no noise, box adopts imported mirror stainless steel plate, durable, beautiful, generous.

5.The whole machine unit structure design ensures the convenient installation, maintenance, maintenance.

6. It adopted microcomputer temperature control and man-machine dialogue, and each point temperature can be real-time displayed.

7. The sample system equipped with six valve and syringe injection in two ways.

8. The instrument can be installed automatic afterwards door opener, has over-temperature protection function, large screen LCD display temperature, external events.
