Ion guide exit transmission control |
abstract |
An ion guide (40) is disclosed that comprises an ion confinement region having a first cross-sectional profile with a first cross-sectional area A1 in a plane orthogonal to a direction of ion transmission. An attenuation device ejects or deflects ions having spatial positions which fall outside of a second cross-sectional profile having a second cross-sectional area A2, wherein A2<A1. |
