Abstract
A method of separating ions according to their ion mobility using an ion mobility separation device including a first section and a second section is disclosed, comprising: urging ions through the first section against a first opposing electric field using a first driving force provided by a first set of time varying voltage(s) or voltage waveform(s); progressively reducing the magnitude of the first opposing electric field and/or progressively increasing the magnitude of the first driving force; and driving ions through the second section against a second opposing electric field using a second drive force provided by a second set of time-varying voltage(s) or voltage waveform(s); wherein the magnitude of the second opposing electric field is progressively reduced and/or the magnitude of the second driving force is progressively increased in tandem with reducing the magnitude of the first opposing electric field and/or increasing the magnitude of the first driving force.
