School of Biological and Chemical Sciences

X-ray diffraction facility

The X-ray Diffraction Facility (XDF) offers a full diffraction analysis service in materials science, structural chemistry, structural biology and solid state science.

The facility is located in the Francis Bancroft building (room G.30) at the Mile End campus, and is shared with the Materials Research Institute

For further information, please visit the XDF website.

Services and equipment

Small molecule diffraction

The new KAPPA APEX ii DUO diffractometer with dual Cu and Mo sources and APEX ii CCD area detector is capable of collecting excellent data for small molecule and protein single crystals.

An Oxford cryostream provides temperature control to –190°C and a diamond anvil cell allows diffraction experiments to be carried out at high pressures (GPa).

The molybdenum sealed tube sources with curved monochromator (Triumph) is for high throughput and charge density measurement, while the low powered air-cooled Copper IμS microfocus tube with doubly curved crystal optic is an excellent source for absolute configuration and protein screening.

Protein crystallography

We use a Rigaku Rotating anode generator with a MAR345 Image Plate detector for protein crystallography.

Powder diffraction facilities

Our powder diffraction facilities include a Panalytical Xpert Pro diffractometer operating in θ/θ geometry for both reflection and transmission, equipped with an Anton Paar strip furnace (25 to 1600°C under vacuum or gas) and a texture cradle.

The Siemens D5000 X-Ray Powder diffractometer Operates in θ/2θ geometry for both reflection and transmission and has a grazing incidence setup for thin films or surface diffraction.

Phase analyses can be rapidly performed using the ICDD PDF4 database and Highscore software.
