A repositionable magnet lets the ion source be removed and replaced without venting the mass spectrometer, cutting downtime and preserving alignment.
Asymmetric protrusions, slots, and keying features prevent misassembly in mass spectrometer maintenance, reducing technician errors and downtime.
A separate heater radiatively warms the cathode to boost electron emission while reducing voltage gradient, filament stress, and hydrocarbon interference.
A variable energy electron ionization source produces abundant molecular and high mass ions by adjusting electron beam energy from 10 eV to 150 eV.
Replacing thermionic filaments with a cold field emission cathode eliminates thermal vaporization and photon emission, reducing signal noise.
A cold electron source uses ultraviolet photons to trigger initial emission in a microchannel plate module for portable mass spectrometry.
