In the Hanson Research Group, optical cells maintain a small volume of gaseous absorbers at controlled conditions. These static cell facilities allow for highly detailed spectroscopic measurements to be performed.
Fourier-Transform Infrared (FTIR) Spectrometer
The FTIR Spectrometer is unique in its ability to measure absorbance across a wide range of wavelengths (1.5–15 µm). This has been utilized to acquire broadband spectra of a wide variety of absorbers, from small molecules (CO, CO2, etc.) to mixtures of hydrocarbons (such as jet fuels).
High-Pressure, High-Temperature (HPHT) Static Cell
The HPHT static cell is capable of temperatures up to 800 K and pressures up to 35 atm. This wide range of conditions supports a variety of different studies, from line-by-line parameter studies to the line mixing characterization of entire absorption bands.
