Abstract
A method of removing sample residue from a surface of a mass spectrometer inlet, with the surface being adjacent to an ion passageway, is provided. A pendent droplet of a cleaning solvent is formed at a tip of a capillary, with the tip being spaced apart from the surface. The pendent droplet detaches from the tip and contacts the surface. The surface is heated to a temperature T at least 50° C. above the boiling point of the least volatile component of the cleaning solvent.
