  • Integrated electrospray emitter and methods for making same
    Patent number: 11845099
    Abstract: An electrospray ionization emitter according to various aspects described herein can include an emitter body formed using fused silica. The emitter body can comprise a fluid conduit segment that includes a liquid connection end that has been coated with polyetheretherketone (PEEK) on at least one portion thereof. The liquid connection end can have a first outer diameter that is configured to be connected to a sample source to receive a sample liquid for ionization therefrom. The emitter body can further comprise an ionization discharge segment that is fluidly connected to the fluid conduit segment. The ionization discharge segment can have an ionization discharge end that is coated with a conductive material on at least one portion thereof and configured to have a second outer diameter that allows ionization of the liquid sample.
