Abstract

An assessment of the high temperature mass spectrometric technique is given, with emphasis on sources of inaccuracy, particularly ionization cross sections. Data -- experimental, calculated, and estimated -- are summarized for ionization cross sections of atoms and inorganic molecules typically found in high temperature vapors. It is concluded that, while much recent progress has been made on the high temperature mass spectrometric technique, the availability of ionization cross sections -- particularly for molecular species -- remains a limiting factor.
