High Temperature Mass Spectrometry

High-temperature mass spectrometry is the most versatile method for the elucidation of vaporization processes. It is shown that by using the mass spectrometers of inorganic solid analysis various non-thermal vaporization processes, not included in the original program of HTMS, can be studied. Comparative investigations are especially useful for elucidating the mechanisms of the rather complex processes in question, opening at the same time new approaches to some basic problems of high temperature science. The investigations proposed, including measurement and analysis of distribution patterns of various related species, stable isotope tracer studies, time resolution studies and quantum chemical calculations, are demonstrated with two examples: the vaporization of alumina and graphite under varied conditions.
