Product Description

GC112N Gas chromatograph is one of widely used analytical instruments. It has become an ideal analytical instrument for separation or analysis in various fields.

Technical Features:


Standard PC control software, built-in chromatographic workstation, achieve PC side reverse control and touch screen synchronous bidirectional control. 
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.
