ABSTRACT:
Analyte ions entrained in a carrier gas are analyzed by parallel flow ion mobility spectrometry prior to analysis by a mass analyzer. An extended ion funnel is located in the vacuum system of the mass analyzer and has an ion focusing section and an ion mobility analyzing section. The carrier gas together with entrained ions is introduced into the ion focusing section where the ions are focused to the axis of the funnel by applied RF voltages. In the ion mobility section, the action of an RF quadrupolar field, the movement of the carrier gas and axial DC field, separates the ions on the basis of their mobilities. The mobility separated ions are released into the mass analyzer where the ions may be further separated on the basis of mass.
