Field desorption
From Mass Spec Terms
| DRAFT DEFINITION |
| Field desorption |
|---|
|
The formation of gas-phase ions from a material deposited on a solid surface in the presence of a high electric field. Because this process may encompass ionization by field ionization or other mechanisms, it is not recommended as a synonym for field desorption ionization. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |

Orange Book Entry
This term is used to describe the formation of ions in the gas phase from a material deposited on a solid surface (known as an ????????????????????????emitter??????????????????????) in the presence of an electric field. As this process probably encompasses ionization by field ionization as well as other mechanisms of ionization the term ????????????????????????field desorption?????????????????????? is not a precise one, despite its widespread acceptance.
