Field desorption (FD)
Deprecated: field desorption ionization.

Formation of gas-phase ions from a material deposited on a solid surface (known as an “emitter”) in the presence of an electric field.

Note: Because this process probably encompasses ionization by field ionization in conjuga- tion with other mechanisms of ionization, the term field desorption ionization, despite its widespread use, is imprecise and therefore not recommended.

Field desorption

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.

Field desorption

http://goldbook.iupac.org/F02357.html

A term 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 a high electrical field. 'Field desorption' is an ambiguous term because it implies that the electric field desorbs a material as an ion from some kind of emitter on which the material is deposited. There is growing evidence that some of the ions formed are due to thermal ionization and some to field ionization of vapour evaporated from material on the emitter. Because there is generally little or no ionization unless the emitter is heated by an electric current, 'field desorption' is a misnomer. The term is, however, firmly implanted in the literature and most users undertand what is going on regardless of the implications of the term. In addition, no better simple term has been suggested to take its place and so, reluctantly, it is recommended that it be retained.
