Abstract
A method for the simultaneous analysis of several elements, in which the analyte, after a thermal vaporization, is athermally excited in the same volume by a hollow cathode discharge, assigns a discharge pressure range, in which the atomization temperature increases steadily with pressure, to the 'cold' and 'hot' hollow cathode discharge. The transition from one range to the other takes place suddenly. The discharge current intensity is increased with increasing atomization temperature.
