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 three-dimensional printed nanospray interface for mass spectrometry may include a body including a sheath inlet connected to a sheath outlet for passage of sheath liquid to an emitter. The emitter may include a sidewall including a stepped texture on an inner surface of the sidewall.

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.
