Technical features:

Standard PC-side anti-control software, built-in chromatography workstation to achieve PC-side anti-control and host touch screen synchronous two-way control. (GC112N only).

The mainframe uses a 7-inch color touch screen, which electronically displays the flow value and pressure value of the air path.

Air shortage alarm: users use to change the column, when opening the door, the motor and heating are all stopped to improve safety.

According to the requirements of users, the shunt ratio is large when working and small when not working, so as to save carrier gas.

The automatic injection port has a positioning function, which makes the injection more efficient and accurate.

The multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.

One-click start function, with 20 groups of sample test mode memory function.

Using logarithmic magnifying board and expandable synchronous external trigger function, the host and workstation can be started at the same time by external signals (automatic sampler, thermal analyzer, etc.).

It has perfect system self-check function and automatic fault identification function.

It has an extended function interface with 8 external events, which can be equipped with various function control valves and work according to its own set timing.

RS232 communication port and LAM network port, and configure data acquisition card.
