<p>A nebulizer assembly (10) particularly well adapted as a liquid chromatograph/mass spectrometer (LC/MS) interface including a pair of nebulizer plates (12,14), a base (16), and a cap (18) for tightly holding the nebulizer plates (12,14) against the base (16). A first nebulizer plate (12) has a centrally located outlet orifice (22) and a radially extending groove (24), and the second plate (14) has a centrally located gas inlet orifice (32) and a radially displaced liquid inlet orifice (34). The gas inlet orifice (32) aligns with the outlet orifice (22) and an aperture (20) provided in the cap (18), and the liquid inlet orifice (34) aligns with a section of the groove (24) provided in the first nebulizer plate (12). When the gas inlet orifice (32) is coupled to a pressurized gas source and the liquid inlet orifice (34) is coupled to a pressurized liquid source, uniform droplets (74) having a diameter of approximately 10 microns can be formed from an outlet orifice (22) twice that diameter.</p> |
