ABSTRACT:
A sample introduction system for ICPMS and ICPAES comprising a nebulizer which sprays liquid samples into a heated cyclonic spray chamber which has a common exit port for both liquid waste and sample aerosol which is coupled to a desolvation system comprised of condenser and revaporization loops that alternately condense solvent vapor both on the inner walls of the loop and in the aerosol stream, then revaporize the portion of solvent condensed in the aerosol stream for subsequent condensation in the next loop. The exit port of the system is capable of being directly or remotely coupled to the ICP injector tube.
