Gas Chromatograph, CA-GC-I112N
- Detector: FID/TCD optional
- 20 groups of sample test mode memory function
- Can match automatic sampler of various specifications
Description
- Standard PC side reverse control software, built-in chromatographic workstation, achieve PC side reverse control and host touch screen synchronous bidirectional control. (GC-I112N only)
- Host with 7-inch color touch screen, carrier/hydrogen/air channel 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.
- The multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.
- One-button start function, with 20 groups of sample test mode memory function.
- Using logarithmic amplifier, detection signal no cut-off value, good peak shape, extensible 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 8 external event extension function interface, can be selected with various function control valves, and according to their own set time sequence work.
- RS232 communication port and LAM network port, and the configuration of data acquisition card.
