Electrospray ionization
From Mass Spec Terms
| DRAFT DEFINITION |
| Electrospray ionization |
|---|
|
A process whereby ionized species in the gas phase are caused from an analyte-containing solution via highly charged fine droplets, by means of spraying the solution from a narrow-bore needle tip at atmospheric pressure in the presence of a high electric field. When a pneumatic assistance is added to the formation of a stable spray, the term pneumatically assisted electrospray ionization is also used (The term ion spray is not recommended?). |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |
| This is an unofficial draft definition presented for information and comment. |
