Abstract
A method for obtaining fragment ions having product ion spectrum with a mixture of high, medium and lower energy product ions. The method includes (a) providing a selected RF field to an ion optical element upstream of an ion containment field; (b) transmitting ions through the ion optical element and into the ion containment field such that the selected RF field determines, at least in part, a selected kinetic energy profile of the ions within the ion containment field, wherein the selected kinetic energy profile is selected to fragment the ions to concurrently provide a plurality of groups of product ions; and (c) detecting each group of product ions in the plurality of groups of product ions.
