Patents by Inventor David G. Mclaren

David G. Mclaren has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11715633
    Abstract: The invention generally relates to systems including nanoelectrospray ionization emitters in a movable array format in which the emitters can be loaded, singly or simultaneously, through their narrow ends using a novel dip and go method based on capillary action, taking up sample from an array. The sample solutions in each emitter can be electrophoretically cleaned, singly or simultaneously, by creating an inductive electric field that moves interfering ions away from the narrow end of the capillary. Subsequent to cleaning, the emitters are supplied with an inductive electric field that causes electrospray into a mass spectrometer allowing mass analysis of the contents of the emitter.
    Type: Grant
    Filed: September 1, 2021
    Date of Patent: August 1, 2023
    Assignee: Purdue Research Foundation
