Basic Gas Chromatograph

GC9802 Basic Gas Chromatograph

Main features

1. Microcomputer temperature control, four-way temperature control, digital display.

2. Two commonly used detectors can be selected at the same time.

3. Near room temperature control function (10℃ above room temperature),

4. The large-capacity column oven has an automatic rear door and can perform 3-stage temperature programming.

5. Can be configured with packed column injector, capillary column injector, gas injector, etc.

6. It has fault self-diagnosis function and can display the fault location and nature at any time.

7. It has over-temperature protection function. If the temperature of any path exceeds the set temperature, heating will automatically stop.
