To Control Ionization. 1  Ionization Voltage Typically, 70eV electrons from the filament are used for EI. 2  Emission Current The number of ions produced in unit time is proportional to the current of emitted electrons, i.e., emission current. 3  Ion Source Temperature The ion source is usually used at about 200 oC.
Animation 5: Exploded diagram of the main components of a typical EI source. 1  Ionization (ion) volume â manufactured from low thermal mass metal, an aperture permits the ingress of electrons to the ion source and a second aperture allows electrons to exit for collection and current monitoring.
