The energy of the electron responsible for the ionisation process can be varied. It must be sufficient to knock out an electron and this threshold, typically about 10-12 eV, is known as the appearance potential. In practice much higher energies (-70 eV) are used and this large excess energy …

detected ions are isolated and undergo no collisions after ionization until they hit the detector. The ion energy, or that energy left to the ion above the ionization energy (ionization potential), is a complex function of the structure and the energetic state of the molecule prior to ionization.
