Abstract
A direct injection micro nebulizer based sample introduction system for use in nebulizing sample solutions in close proximity to sample analysis systems, with desolvation and solvent removal capability is disclosed. The present invention offers design features and utility not available in previously known micro nebulizer systems. Predominantly unibody design and use of nonmetalic, hydrofloric acid resistant construction materials are taught. The present invention allows easy cleaning and adjustment of element relationships which are necessary to proper operation of direct injection micro nebulizer systems. Use of separate or integrated protective sleeving on otherwise crushable sample solution delivery tubing is disclosed. Special direct injection micro nebulizer top elements and torch designs are also disclosed.
