Abstract

An inductively coupled plasma (ICP) torch includes: an injector defining an injector flow passage to receive a flow of a sample fluid; a plurality of tubes disposed about the injector and configured to receive and direct a flow of one or more torch gases; an induction device disposed about the plurality of tubes, the induction device configured to receive a radio-frequency electric current to inductively energize at least one of the one or more torch gases to produce a plasma proximate a distal end of the ICP torch; and a plasma steering system including a plurality of nozzles adjacent a distal end of the injector flow passage and configured to receive and direct a flow of steering fluid to impinge and redirect the flow of sample fluid and to thereby redirect an ionized sample resulting from the interaction of the sample fluid with the plasma.
