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.
