Hydrostatic low-range pressure applications of the Paris-Edinburgh cell utilizing polymer gaskets for diffuse X-ray scattering measurements.

The use of a polymeric Torlon (polyamide-imide) gasket material in a Paris-Edinburgh pressure cell for in situ high-pressure X-ray scattering measurements is demonstrated. The relatively low bulk modulus of the gasket allows for fine control of the sample pressure over the range 0.01-0.42 GPa. The quality of the data obtained in this way is suitable for Bragg and pair distribution function analysis.
