Abstract

Packed-tip electrospray ionization (ESI) emitters for mass spectrometry are described. In one aspect an ESI emitter stores a first type of particle. A liquid chromatography (LC) column is coupled with the emitter via a junction. The LC column stores a different type of particle than the ESI emitter to facilitate better chromatographic and ESI performance.
