Aerosol collection and rf plasma volatilization on a tungsten wire electrode.
Electrostatic trapping of desolvated aerosols on a wire electrode is described. A capacitively-coupled radiofrequency discharge is used to vaporize and excite collected material. The apparatus shows a clear and controllable transition between different modes of electrostatic collection. Boron shows unexplained anomalous behaviour.
