Micro concentric tube nebulizer for coupling liquid devices to chemical analysis devices

摘要

A method and apparatus for improving pneumatic nebulization of liquids is taught providing for controllable production of droplet size range generated. The improvement is aimed at nebulizers comprised of concentric tubes, the inner transporting analyte liquid, the outer-- inert gas. The improvement comprises altering the outer lip of the free end of the inner tube so as to allow laminar flow of the exiting gas. By alteration of the tip, droplets in a controlled size range can be routinely produced with a minimum of operator adjusting.
