1.It is used to detect the solvent residue in packaging and printed products.

2.It is used to detect the purity and content of solvents.

3.Detectable substances: benzene, cyclohexanone, xylene, ethanol, ethylbenzene, isopropanol, propanol, butanol, ethyl acetate, isopropyl acetate, n-butanol, toluene, n-butyl acetate, phosmet, 4-methyl-2-pentanone, etc.

A gas chromatograph is a tool for the separation and analysis of multi-component mixtures. It uses an inert gas as the mobile phase and adopts chromatographic column separation technology. When multiple substances to be analyzed enter the chromatographic column, due to the different distribution coefficients of each component in the chromatographic column, the flow rates of each component in the chromatographic column are different. After passing through a certain column length, the mixed components leave the chromatographic column separately and enter the detector. After detection, they are converted into electrical signals and sent to the data processing workstation, thus completing the detection and analysis of the substances to be measured.

1.It is equipped with a 7inch color touch - screen for intelligent interaction. The newly - developed intelligent operating system it carries features a simple and intuitive interface similar to that of a smartphone, with a clear and straightforward operation logic.

2.It allows the optional configuration of multiple commonly - used detectors simultaneously at most.

3.It has adjustable split and makeup gas functions, which improve the testing accuracy.

4.It is furnished with an automatic rear - door opening system for the column oven. This enhances the ability to control the temperature close to room temperature. It supports programmed temperature operation, with faster heating and cooling rates. Each heating control unit is equipped with an over - temperature protection function.

5.It can be configured with various devices such as packed column injectors, capillary column injectors, automatic liquid injectors, gas valve injectors, nickel converters, thermal desorption injectors, headspace automatic injectors, and pyrolysis injectors.

6.It has a self - diagnostic function for faults, which can display the location and nature of the fault at any time. It also has an over - temperature protection function. If the temperature of any channel exceeds the set value, the heating will automatically stop and an alarm will be triggered.

7.It can be connected to a chromatography workstation, presenting experimental results in an intuitive and clear manner.

8.With an advanced noise suppression system, it can completely eliminate the fan noise during operation, creating a comfortable and quiet working environment.

9.The flexible design of packed and capillary column injection ports allows users to make choices according to actual situations. The spacious column oven facilitates complex analysis tasks and the use of multiple chromatography columns, expanding the scope of analyzable samples.

10.Controlled by a microcomputer, it enables human - machine interaction to display various required temperatures. The temperature control range of the column oven is from (room temperature + 10°C) to 300°C, with a temperature control accuracy of 0.1%.

11.The over - heating protection function can be set within any range up to 400°C, with dual - insurance protection provided by both software programs and hardware circuits.

12.It is equipped with an automatic ignition function.
