A high‐temperature infrared absorption gas sample cell
Autor: B. J. Brashear, J. H. Welch, W. J. Phillips
Publikováno v: Review of Scientific Instruments. 63:2174-2176
An infrared absorption sample cell was designed and constructed for use in the temperature range from 300 to 1000 K. The design’s emphasis was on maintaining an inert environment to eliminate the possibility of depleting the absorbing gas due to re
