Thermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are ionized. Thermal ionization is used to make simple ion sources, for mass spectrometry and for generating ion beams. Thermal ionization has seen extensive use in determining atomic weights, in addition to being used in many geological/nuclear applications. danceworks studio redmond waWeb17 sep. 2024 · Consideration should therefore be given to the type of fire detector in order to reduce the amount of unwanted false alarms.
