摘要
In an ion trap (10) a trapping field is established such that ions of interest are stably held within the trap (10). A parent ion of interest is isolated in the ion trap (10). A prescan is performed using ionisation parameters that are calculated determined from a prior scan of the ion trap (10), wherein the parent ion was isolated in the ion trap (10) during the prior scan. Then an analytical scan of the ion trap (10) is performed.
