ABSTRACT:
A system atomizes liquids into a gaseous medium for formation and injection of a sample into an analytical apparatus, such as a plasma spectrometer. The system employs a high efficiency nebulizer that generates a fine aerosol through use of a nozzle having improved surface wetness characteristics, preferably in combination with a deflecting surface. A desolvator is employed to remove excess solvent from the atomized sample prior to injection into the spectrometer to avoid temperature reduction or extinguishment of the plasma by the sample.
