| DRAFT DEFINITION |
| Electrospray ionization |
|---|
|
A process in which ionized species in the gas phase are produced 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 presurized gas is used to aid in the formation of a stable spray, the term pneumatically assisted electrospray ionization is used. The term ion spray is not recommended. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |
