ELECTRIC-ARC DOUBLE JET PLAZMATRON FOR SPECTRUM ANALYSIS

摘要

An electric-arc double jet plazmatron for spectrum analysis.The invention relates to the spectrum analysis technique, in particular, to an electric-arc plazmatron for spectrum analysis. The aim of the invention is to increase spectrum analysis sensitivity with lesser gas consumption and lesser current strength caused by the change in the plazmatron design. To provide maximum approach of the plazmatron jets cuts are made in torch heads at 30° to the plasma canal axis, the cuts are spaced at a distance of 1/3 a nozzle portion from facing each other nozzle holes.
