X-ray Diffraction

The Chemistry Department maintains an X-ray diffraction facility for determining the crystal structures of compounds of interest to faculty and students in the Department.  The facility houses a Bruker SMART diffractometer with an Apex II detector.   This diffractometer is capable of high throughput data collection on large crystals, but structures have been solved for light atom crystals as small as 10 microns across.  The system is cooled by a state-of-the-art gaseous N2/He cryostat, the Oxford Cryosystems N-Helix, which can reach temperatures as low as 22 K.  The instrument is also equipped with an optical heating and crystallization device (OHCD).  The OHCD allows single crystals to be grown on the diffractometer at low temperatures allowing for the collection of low melting and air sensitive samples which cannot be handled under ambient conditions.
