Abstract: In some examples, an ion funnel-based collision cell may include an ion funnel entrance section formed by a plurality of adjacently disposed entrance members. Each entrance member of at least one pair of the adjacently disposed entrance members may include a successively larger opening to form a tapered or profiled entrance for ions entering the ion funnel-based collision cell. An insulation material may be disposed adjacent to or in contact with each entrance member of the at least one pair of the adjacently disposed entrance members to prevent, outside of each successively larger opening, flow of gas between each entrance member of the at least one pair of the adjacently disposed entrance members.

Abstract: In some examples, a multipole section-based ion funnel may include an ion funnel section formed by at least one pair of adjacently disposed members. A first member of the at least one pair of adjacently disposed members may include a pole structure. A second member of the at least one pair of adjacently disposed members may include a pole structure that is engageable with the pole structure of the first member to form a multipole structure.

Abstract: An ion source may include an ionization chamber to be maintained at atmospheric-pressure. The ion source may further include a reduced-pressure chamber to be maintained at sub-atmospheric pressure, and an ion transfer device comprising an inlet in the ionization chamber and an outlet in the reduced-pressure chamber. The ion transfer device may define an ion path from the inlet to the outlet. The ion transfer device may be positioned to emit ions and neutral gas molecules from the outlet as an expanding beam comprising a low-gas density zone enveloped by a high-gas density region that includes a gas density that is higher than the low-gas density zone. The ion source may be utilized, for example, for ion mobility spectrometry (IMS), mass spectrometry (MS), and hybrid IM-MS.
