Abstract
A sample inlet device and methods for use of the sample inlet device are described that include an ion funnel having a plurality of electrodes with apertures arranged about an axis extending from an inlet of the ion funnel to an outlet of the ion funnel, the ion funnel including a plurality of spacer elements disposed coaxially with the plurality of electrodes, each of the plurality of spacer elements being positioned between one or two adjacent electrodes, each of the plurality of spacer elements having an aperture with a diameter that is greater than a diameter of each adjacent electrode. The ion funnel is configured to pass an ion sample through the apertures of the electrodes and the spacer elements to additional portions of a detection system, such as to a mass analyzer system and detector.
