Abstract: A wall-stabilized electric arc within a capillary tube, supported by a gas flowing lengthwise through the tube is used to excite a material for spectroscopic analysis. A material to be analyzed, in gaseous or finely comminuted form, is fed into the arc near one end and carried through it by the working gas. Emission or absorption of radiation is observed endwise of the tube.
