Abstract:
Proton transfer reaction mass spectrometry (PTRMS) is a kind of mass spectrometry based on chemical ionization. The ion source and drift tube of PTR-MS are supplied by DC high voltage, and the instrument only run stably in a high vacuum environment. In order to ensure the safe and stable operation of the instrument, this paper designs a power supply and vacuum control system based on LPC1788 chip, and uses CAN bus to realize the communication between the host computer and the main controller. It was applied to PTR-MS developed in laboratory.
