X-ray crystallography

A purpose-built crystallography laboratory houses 3 single crystal diffractometers and one powder diffractometer.

All of the single crystal diffractometers are equipped with modern kappa-geometry goniometers. Two of these have conventional fixed Mo-anode X-ray tubes and are used for routine samples. The third is a very high intensity rotating Cu-anode instrument with beam focussing optics and a large format area detector. This instrument is used for studying weakly diffracting, disordered and twinned crystals with results second only to those that could be obtained at a synchrotron source.

The laboratory also houses a high throughput powder X-ray diffractometer equipped with a linear detector, robotic sample changer and 30 silicon wafer sample holders. This allows powder diffraction data for a sub-milligram quantity of sample to be collected in minutes.
