Patent number: 11830717Abstract: The invention generally relates to apparatuses for focusing ions at or above ambient pressure and methods of use thereof. In certain embodiments, the invention provides an apparatus for focusing ions that includes an electrode having a cavity, at least one inlet within the electrode configured to operatively couple with an ionization source, such that discharge generated by the ionization source is injected into the cavity of the electrode, and an outlet. The cavity in the electrode is shaped such that upon application of voltage to the electrode, ions within the cavity are focused and directed to the outlet, which is positioned such that a proximal end of the outlet receives the focused ions and a distal end of the outlet is open to ambient pressure.Type: GrantFiled: April 14, 2023Date of Patent: November 28, 2023Assignee: Purdue Research FoundationInventors: Robert Graham Cooks, Zane Baird, Wen-Ping Peng

Publication number: 20230197433Abstract: The invention generally relates to systems and methods for separating ions at about or above atmospheric pressure. In certain embodiments, the invention provides systems that include an ionization source that generates ions and an ion trap. The ion trap is maintained at about or above atmospheric pressure and includes a plurality of electrodes and at least one inlet configured to receive a gas flow and at least one outlet. The system is configured such that a combination of a gas flow and one or more electric fields produced by the electrodes separates the ions based on mass-to-charge ratio and sends the separated ions through the at least one outlet of the ion trap.Type: ApplicationFiled: February 10, 2023Publication date: June 22, 2023Inventors: Robert Graham Cooks, Dalton Snyder, Amar S. Basu, Wen-Ping Peng
