| Firstly, there is no charge separation or corresponding Coulomb attraction barrier, because the electron is ejected and hydrated in the bulk directly by photoionization. |
| Heraeus Noblelight lamps include Deuterium, Tungsten-Halogen, Spectral Line Sources, Photoionization, Mercury, Hollow Cathode and more. |
| Photoionization detectors, for example, can be used to watch solvent exposures, or light scattering can monitor exposure to aerosols. |
| The Dräger X-am 7000 can be equipped with three electrochemical and two infrared, catalytic sensors or photoionization detectors. |
| The main source of light absorption in the hotter stars is the photoionization of hydrogen atoms, both from ground level and from higher levels. |
| This is known as the Auger effect or autoionization since the ion has self-ionized after the photoionization event. |
