Supply and Control of Electrodynamic Traps

CGC Instruments has many years of experience in developing hardware for ion traps, mass spectrometers, electron and ion optics, as well as electronic devices for controlling these systems.
Many of our products, including switches, (pre-)amplifiers, generators, power supplies, and counter or timer modules for our modular DAQ system, were specifically designed for applications such as:
  • Ion traps
  • Traps for nano- or microparticles
  • Quadrupole mass filters
  • Ion guides
  • Mass-selected ion deposition
  • Electrospray ion sources
If desired, we will calculate the operating parameters required for your trap or ion guide. Simply contact us with the necessary details your multipole type and dimensions, the mass range of the ions or particles, as well as their transverse kinetic temperature / energy.
