Abstract

Passage of radio frequency current through a large diameter ferromagnetic wire gives rise to surface heating. This happens because of maximum skin effect resistance and eddy current loss at the surface of such wire. This phenomenon was successfully exploited for desorption of five thermolabile as well as many volatile compounds. The desorbed molecules were subjected to EI and/or CI ionization in a double focussing mass spectrometer. Results show that this method of desorption compared favorably with others for mass spectral analysis.
