Technical Features:

Standard PC Terminal anti-control software, built-in chromatography workstation to realize PC Simultaneous bidirectional control and host touch screen are controlled by two-way.

The host uses a 7-inch color touch screen, and the sampler and detection system use electronic flow /Electronic pressure control system ( EFC/EPC）。

Have air loss alarm protection function； Heating control protection function (the column box fan motor and heating system are automatically closed when opening the column box door during use).

Split flow /The shunt ratio can be automatically controlled to save carrier gas.

Configure the automatic sampler installation positioning interface to match the automatic sampler of each specification.

The user-friendly one-click start function and a multi-core 32-bit embedded hardware system ensure the reliable operation of the instrument.

Using logarithmic amplifier, the detection signal has no cutoff value, good peak shape, and can be expanded synchronized external trigger function, which can be obtained by external signals. (Automatic sampler, thermal analyzer, etc. )Start the host and workstation at the same time.

It has complete system self-test function and automatic fault identification function.

It has an extended function interface with 8 external events, and can be equipped with various functional control valves and operate in the set timing of your own.

Equipped RS232 Communication port and LAM Network port, memory call function of 20 groups of sample testing methods.
