Apparatus for the Study of Hydrothermal Reactions by Real-Time "in situ" X-Ray Diffraction

The pressure cell is capable of studying reactions at temperatures of up to 250°C and pressures up to 400psi. An internal Teflon liner minimises contact between the reagents and cell and permits the study of corrosive reaction mixtures. The cell design relies on several of the unique features of synchrotron radiation. Firstly, the polychromatic nature of the beam lends itself to energy-dispersive diffraction, which means that only small sample windows are required. Secondly, the high intensity and low attenuation of the beam mean that good quality spectra can be recorded within minutes even through a 2 mm thickness of stainless steel.
