Technical features: The host adopts a 7-inch color touch screen, with a user-friendly human-machine exchange interface.
The computer reverse control and the host touch screen achieve synchronous bidirectional control.
A multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.
Digital display of carrier gas/hydrogen/air flow rate (pressure).
Equipped with air shortage alarm protection function; Heating control protection function (when the column box door is opened during use, the column box fan motor and heating system will automatically shut down).
The split flow rate/split ratio can be automatically controlled to save carrier gas.
Configure the installation and positioning interface of the automatic sampler, and match it with various specifications of automatic samplers.
The data collection is equipped with a standard dual channel data acquisition card, with a sampling time of 50ms.
Using a logarithmic amplification board, the detection signal has no cut-off value, and the synchronous external trigger function can be used to start both the host and workstation simultaneously by external signals (such as automatic samplers, thermal analyzers, etc.).
Equipped with comprehensive system self inspection function and automatic fault identification function.
It has an extended functional interface with 8 external events, and can be equipped with various control valves to work according to its own set timing.
The external connection method is through Ethernet port connection (RJ45), providing convenience for remote control of data.
In addition to the independent heating zone of the column box, there are also 6 heating zones. Two heating zones for injection ports, two heating zones for detectors, and two auxiliary heating zones.
The maximum operating temperature of the auxiliary heating zone can reach 400 ºC
