Continuous-flow sample cell for X-ray absorption spectroscopy

A Swiss group has reported on the design and performance of a novel high-temperature and high-pressure continuous-flow reactor, which allows for X-ray absorption spectroscopy or diffraction in supercritical water and other fluids under high pressure (up to 30 MPa) and temperature (up to 500 ^oC). For more information, see the paper,"Design of a continuous-flow reactor for in situ x-ray absorption spectroscopy of solids in supercritical fluids", M. Dreher et al., Rev. Sci. Instrum. 83, 054101 (2012).
