Gas Chromatograph Feature:

  1. The 7-inch color touch screen directly displays the values of hydrogen/carrier gas/air channel flow (pressure), which is very convenient.

  2. Gas shortage alarm and heating control protection function make the gas chromatograph safer.

  3. One-touch start-up saves time.

  4. Split flow/split ratio can be automatically controlled to save carrier gas.

  5. Configuration of autosampler mounting and positioning interface, matching various specifications of autosampler.

  6. A multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.

  7. With 20 groups of samples, the test pattern memory function can easily view the previous test data.

  8. Adopt logarithmic amplifier, no cut-off value of detection signal, good peak shape.

  9. Synchronous external trigger function can start the host computer and workstation at the same time through the external signal.

  10. With perfect system self-test function and automatic fault identification function.

  11. With eight external events to expand the function interface, you can choose a variety of functions control valves.
