Abstract
A novel curved collision cell for a mass spectrometer is described. The collision cell includes a straight section having a length that is selected to cause a precursor ion entering the straight section to lose a desired amount of kinetic energy such that when the precursor ion enters the curved section of the collision cell the precursor ion will tend to neither escape nor contact the collision cell, and thereby tending to survive its passage within the curved portion.
