- A ceramic gas cell designed for gas measurements up to 1300Â K and 200Â bar.
- The first recorded absorption spectrum of CO2 at 1000Â K and 101Â bar is presented.
- Voigt profiles might suffice in the modeling of radiation from CO2 in combustion.
A high temperature and high pressure gas cell (HTPGC) has been manufactured for quantitative spectroscopic measurements in the pressure range 1-200Â bar and temperature range 300-1300Â K. In the present work the cell was employed at up to 100Â bar and 1000Â K, and measured absorption coefficients of a CO2-N2 mixture at 100Â bar and 1000Â K are revealed for the first time, exceeding the high temperature and pressure combinations previously reported. This paper discusses the design considerations involved in the construction of the cell and presents validation measurements compared against simulated spectra, as well as published experimental data.
