GC112A
Gas Chromatograph
Technical Features
● 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.
