The two Bruker D8 powder diffractometers (primary monochromatic CuKα radiation) operate in both reflection (flat plate) and transmission (flat plate or capillary) geometries. Both instruments are equipped with a position-sensitive detector allowing rapid data collection for qualitative and quantitative identification of crystalline phases, such as polymorphs. Powder patterns can often be obtained from only a few mg of sample, although bulk sample holders are also available. More advanced applications, such as structure solution of inorganic, organic and pharmaceutical materials, Rietveld refinement, and particle size/ strain analysis are also possible. One of the diffractometers is equipped with a sample-changing robot, allowing the collection of data from up to 90 samples, which provides a useful facility for users requiring high throughput. Variable temperature stages on the second instrument allow data to be recorded under vacuum at temperatures between 90 and 1473 K (-183 and 1200 °C) or under humidity controlled conditions at temperatures up to 473 K (200 °C). Such data are suitable for phase-transition and hydration/dehydrations studies. We can offer data collection only, routine characterisation and ‘advanced applications’ as above. Again full structural reports are available in standard formats.
