Mass Spectrometry Techniques and Applications

On the hardware platform with single CYCLONE IV FPGA Chip based on SOPC technology, the control functions of IP cores of a Ion Mobility Spectrometry instrument was tested, including 32 bit Nios II soft-core processor, high-voltage module, ion gate switch, gas flow, temperature and pressure sensors, signal acquisition and communication protocol. Embedded operating system μCLinux was successfully transplanted to the hardware platform, used to schedule all the tasks, such as system initialization, parameter setting, signal processing, recognition algorithm and results display. The system was validated using the IMS diagram of Acetone reagent, and the instrument was proved to have a strong signal resolution.
