The GC126N gas chromatograph sample injector and detection system adopts a logarithmic amplifier board, and the detection signal has no cutoff value. The synchronous external trigger function can start the host and workstation at the same time by an external signal (automatic sample injector, thermal analyzer, etc.).
1. The host machine adopts a 7-inch color touch screen with friendly man-machine interface.
2. Computer backcontrol and host touch screen to achieve synchronous bidirectional control.
3. The multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.
4. Carrier/hydrogen/air flow (pressure) digital display.
5. 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).
6. Split flow/split ratio can be automatically controlled to save carrier gas.
7. Configure automatic sampler installation and positioning interface to match automatic sampler of various specifications.
8. Data acquisition is a standard dual-channel data acquisition card with a sampling time of 50ms.
9. 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.
10. It has perfect system self-check function and fault automatic identification function.
11. 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.
12. The external link mode is network port connection (RJ45), which provides convenience for remote control of data.
