[ I ] Ionization voltage. [Synonym] Ionization potential. [ II ] Ionizing voltage. This refers to the accelerating voltage that gives energy to electrons in order to ionize gas or vapor by electron bombardment in a mass spectrometer. In quantitative analysis, a voltage of 50 to 100 V is used, since the ratio of fragment ions produced during ionization does not change much with electron energy.
