Stable ion
From Mass Spec Terms
| DRAFT DEFINITION | 
| Stable ion | 
|---|
| An ion with internal energy below the threshold for dissociation or isomerization (not sufficiently excited) which therefore does not dissociate, rearrange nor react spontaneously when flying inside a mass spectrometer reaching the detector in its intact form (configuration and connectivity). | 
| Considered between 2004 and 2006 but not included in the 2006 PAC submission | 
| This is an unofficial draft definition presented for information and comment. | 
Orange Book Entry
An ion which is not sufficiently excited to dissociate spontaneously into a Daughter Ion and associated neutral fragment(s) or to react further before reaching the detector.
