GC126N
Gas Chromatograph
Technical Features
● The host machine adopts a 7-inch color touch screen with friendly man-machine interface.
● Computer backcontrol and host touch screen to achieve synchronous bidirectional control.
● The multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.
● Carrier/hydrogen/air flow (pressure) digital display.
● Gas shortage alarm protection function; Heating control protection function (when opening the door of the column box, the motor of the column box fan and the heating system will shut down automatically).
● Split flow/split ratio can be automatically controlled to save carrier gas.
● Configure automatic sampler installation and positioning interface to match automatic sampler of various specifications.
● Data acquisition is a standard dual-channel data acquisition card with a sampling time of 50ms.
● Using logarithmic amplification plate, detection signal no cut-off value, synchronous external trigger function, can be started by external signals (automatic sampler, thermal analyzer, etc.) at the same time the host and workstation.
● It has perfect system self-check function and fault automatic identification function.
● With eight external event extension function interface, can be selected with a variety of control valves, and according to their own set time sequence work.
● The external link mode is network port connection (RJ45), which provides convenience for remote control of data.
