The circuit system of the gas chromatography vials mainly includes temperature control system, amplifier system, display system, keyboard system, power system, communication system, foreign affairs control system and so on. The most widely used in the gas chromatograph is the distributed control system. The system requires that the circuits of the same function be unified into modules according to functions. The whole circuit is composed of a plurality of different modules, and the communication between the modules is performed by means of a bus. The control is coordinated by a main CPU to complete the overall control of the instrument. Most instruments on the market currently gas chromatography vials use a distributed control system.
This is the end of the introduction of Structure of the gas chromatograph circuit system. I hope it can help you.
