Abstract
An apparatus for the production of aerosols from liquid samples for elemental analysis comprises means for generating droplets of the liquid sample (1), and means for subjecting the droplets so formed to rapid radiative heating (2, 21, 22) so as to evaporate liquid from the sample droplets. The heating means preferably comprises a heating chamber (2) positioned at one focus of a reflector (22) and a heat-bar (21) positioned at the other focus.
