Abstract
A direct injection micro nebulizer system for use in nebulizing sample solutions in close proximity to sample analysis systems, is disclosed. The present invention offers design features and utility not available in previously known micro nebulizer systems. The present invention, preferrably, provides single piece unibody construction of the primary body element, and construction of all element thereof from nonmetallic, hydrofloric acid resistant materials. 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 also disclosed. Use of the direct injection micro nebulizer with standard and specially designed inductively coupled plasma torches, as well as other sample analysis systems is disclosed.
