Laser-Assisted Vaporization Mass Spectrometry: Application to Thermochemistry at Very High Temperatures.

摘要

Classical mass spectrometrically-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, the authors 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 techniques to ceramics and other refractory systems.
