SHEATH-FLOW ELECTROSPRAY INTERFACE

摘要

A sheath-flow interface for producing electrospray from a capillary is provided. The electrospray generated by the interface can be used as the source of ions for mass spectrometry. In the interface, electrokinetic flow moves a sheath liquid past the end of a capillary so as to mix with an analyte effluent discharged from the capillary. The mixture of sheath liquid and analyte is directed to an electrospray emitter in order to generate an electrospray.
