Abstract
A nebulizer assembly particularly well adapted as a liquid chromatograph/mass spectrometer interface including a pair of nebulizer plates, a base, and a cap for tightly holding the nebulizer plates against the base. A first nebulizer plate has a centrally located outlet orifice and a radially extending groove, and the second plate has a centrally located gas inlet orifice and a radially displaced liquid inlet orifice. The gas inlet orifice aligns with the outlet orifice and an aperture provided in the cap, and the liquid inlet orifice aligns with a section of the groove provided in the first nebulizer plate. When the gas inlet orifice is coupled to a pressurized gas source and the liquid inlet orifice is coupled to a pressurized liquid source, uniform droplets having a diameter of approximately 10 microns can be formed from an outlet orifice twice that diameter.
