High Pressure and Temperature Infrared Gas Cells [PDF]
Applied Spectroscopy, 1977 In the literature the construction of some high pressure infrared gas cells has been described. However, these cells show, just as the commercially available high pressure gas cells, many problems with the cell windows. For our research on infrared integrated intensities we needed reliable pressure cells, which could be used at pressures up to 90 atm ...

High temperature and pressure electrochemical test station [PDF]
Review of Scientific Instruments, 2013 An electrochemical test station capable of operating at pressures up to 100 bars and temperatures up to 400 °C has been established. It enables control of the partial pressures and mass flow of O2, N2, H2, CO2, and H2O in a single or dual environment arrangement, measurements with highly corrosive media, as well as localized sampling of gas evolved at ...
