On-line reaction monitoring is an important tool in the development of new processes. Supercritical water, sch2O presents particular challenges to the spectroscopist - high temperatures, and very intense IR bands which obscure large regions of the spectrum.
We have been fortunate to have had a very fruitful collaboration with Professor Y U Gorbaty at the Institute of Experimental Mineralogy, Chernogolovka, Russia. This has resulted in the development of a series of spectroscopic cells for scH2O with outstanding performance
