High temperature sample heating for spectroscopic studies apparatus

摘要

In accordance with the invention, an improved sample heating apparatus is provided comprising an evacuated cylindrical envelope having a first portion of reduced diameter and capable of fitting into a cavity of a spectroscopic analysis device and capable of receiving a sample holder therein. A second portion of the cylindrical envelope has a larger diameter and heating means mounted therein. Radiation shielding means are also carried within the evacuated envelope of the larger diameter portion. The apparatus is also provided with gettering means to react with gases within the evacuated envelope.
