    Abstract: An analyte material is prepared for spectrochemical analysis by depositing it in solution or electrostatically precipitating it upon a previously purged yarn of finely divided carbon fibers, dessicating it in situ, and electrically heating the yarn sufficiently to vaporize the analyte material while passing a gas stream over it in which the analyte material is condensed in particles of sufficiently small size to form an aerosol which is then conducted to any of a variety of excitation sources for spectrochemical analysis.

    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.
