Precursor ion scan
From Mass Spec Terms
| DRAFT DEFINITION |
| Precursor ion scan |
|---|
|
For sector instruments: 1. Mass selection followed by ion kinetic energy analysis- If a precursor ion is selected by a magnetic sector all product ions formed from it in the field-free region between the magnetic sector and a flowing electric sector can be identified by scanning an ion kinetic energy spectrum. 2. Linked scan at constant B/E or at constant E2/V ?????????????????????????? Both of these linked scans give a spectrum of all product ions formed from a pre-selected precursor ion. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |
| This is an unofficial draft definition presented for information and comment. |
