Abstract
A Taylor cone emitter device is disclosed, including a substrate, a sorbent layer on at least a portion of the substrate, a Taylor cone emitter portion extending from the substrate, and a reservoir surface configured to retain a liquid and feed the liquid to the Taylor cone emitter portion while a Taylor cone is emitted from the Taylor cone emitter portion. The Taylor cone emitter portion is free of sharp features having an edge or point with a radius of curvature of less than 250 μm and includes a broadly curved surface having a radius of curvature of at least 300 μm from which the Taylor cone emanates. A Taylor cone analysis system is disclosed, including an analytical instrument having a sample inlet, the Taylor cone emitter device, and at least one electric field lens configured to tune Taylor cone generation from the Taylor cone emitter portion.
