Abstract : The general concept of a probe system is described that will allow the mass spectrometric analysis of the pressure environments near 1 atmosphere and above which are of current practical interest. Applications include the detection of both the stable and highly unstable gas molecules present in reacting mixtures and determining the vapor species existing over reacting solids in any temperature range. Illustrative examples are given to show some of the kinds of important materials problems whose solutions may be speeded by application of this device. The current development status and the major remaining problems associated with this device are summarized. (Author)
