From Mass Spec Terms
DRAFT DEFINITION |
Flowing afterglow |
---|
An ion source immersed in a flow of helium or other inert buffer gas that carries the ions through a meter-long reactor at pressures around 100 Pa. |
Considered between 2004 and 2006 but not included in the 2006 PAC submission |

ASMS TERMS AND DEFINITIONS POSTER ENTRY |
Flowing afterglow |
---|
a reactor for observing ion-molecule reactions, in which ions are introduced to a bath gas containing a neutral reactant, and flowing rapidly down a vacuum system, where neutral pressure and distance become the reaction variables. Detection of the ions is by mass spectrometry through a leak at the product end of the system. |
