Abstract

Classical mass spectrometically-based approaches to the determination of high temperature thermochemical data and functions are limited in their applicable ranges of temperature and vapor pressure. An earlier laser-based mass spectrometric approach substantially overcame these limitations, but with reduced precision in temperature and pressure determination. Here, we present new methods that largely resolve the earlier limitations of laser-assisted vaporization mass spectrometry, thereby greatly expanding the scope of application of high temperature mass spectrometric technique.
