Abstract
Solid powder samples deposited on Ag thin films are electrically vaporized by capacitive discharge. The aerosol produced by this method is introduced into the ICP. A low-volume vaporization chamber has been designed for these experiments. A magnetic field of a few kG normal to the electric field in the thin-film plasma is used to improve the plasma/sample interaction. A continuous flow of Ar or 60%/40% Ar/O2 through the chamber carries the aerosol from the capacitive discharge plasma into the ICP. Analytical data will be presented for a number of NIST reference materials emphasizing the determination of Mn, V, and Ni in biological and refractory inorganic matrices.
