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.

1.7 inch color touch screen for intelligent interaction. Equipped with a new generation of intelligent operating system, it has a simple and intuitive interactive interface similar to that of a smart phone, with a clear and understandable operation logic.

2.Multiple commonly used detectors can be optionally configured simultaneously at most. It can be connected to a chromatographic workstation, and the experimental results are intuitive and clear.

3.The large-capacity column oven has an automatic rear door opening function for rapid cooling.

4.It can be configured with devices such as packed column samplers, capillary column samplers, automatic liquid samplers, gas valve sampling devices, nickel conversion furnaces, thermal desorption samplers, headspace automatic samplers, and pyrolysis samplers.

5.It has a fault self-diagnosis function, which can display the fault location and nature at any time; it has an over-temperature protection function. When the temperature of any channel exceeds the set temperature, it will automatically stop heating and give an alarm.

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

7.Flexible design of packed column and capillary column injection ports, which can be selected according to the actual situation; the large column oven provides convenience for complex analysis tasks and the use of various chromatographic columns, expanding the range of samples for analysis.

8.Controlled by a microcomputer, it can conduct human-machine dialogue and display various required temperatures. The temperature control range of the column oven is (room temperature + 10℃) - 300℃, and the temperature control accuracy is 0.1%.

9.Overheating protection function: It can be set within any range up to 400℃, with software program protection and dual insurance protection of the hardware circuit.
