  • Optical bench for a mass spectrometer system
    Patent number: 7442920
    Abstract: Mass spectrometer systems for measuring mass/charge ratios of analytes are described. A mass spectrometer system includes a vacuum flange, a PCB base plate coupled to the vacuum flange, and an ion optic assembly coupled to the PCB base plate. The PCB base plate may include signal-processing electronics. The system may include an electrical cable coupled to the PCB base plate for supplying power, control, and I/O to the ion optic assembly and the signal processing electronics. Alternatively, a mass spectrometer system includes a PCB base plate and an ion optic assembly. The PCB base plate has a sealant portion and an electrical portion. The ion optic assembly is coupled to the electrical portion. The system may include a vacuum housing for enclosing the ion optic assembly. The vacuum housing is coupled to the sealant portion of the PCB base plate for sustaining a vacuum while the system is in operation.
