Buy Gas Chromatography Machine Factories - Gas Chromatograph – NANBEI

Features

● The host adopts a 7-inch color touch screen with digital display of the flow (pressure) of the carrier gas/hydrogen/air channel.
● Lack of air alarm protection function; heating control protection function (when the oven door is opened, the oven fan motor and heating system are automatically turned off).
● The split/split ratio can be automatically controlled to save carrier gas.
● Configure autosampler to install positioning interface to match various specifications of autosampler.
● Multi-core 32-bit embedded hardware system to ensure reliable operation of the instrument.
● One-key start function, with 20 sets of sample test mode memory function.
● Logarithmic amplifier is adopted, the detection signal has no cut-off value, the peak shape is good, and the synchronous external trigger function can be expanded. The host and workstation can be started at the same time through external signals (autosampler, thermal analyzer, etc.).
● It has a perfect system self-check function and automatic fault identification function.
● With 8 external event expansion function interfaces, various function control valves can be selected, and work according to the time sequence set by yourself.
● RS232 communication port and LAM network port, as well as the configuration of the data acquisition card.
