X-Ray Crystallographic Laboratory @ University of Minnesota
The XCL accepts samples for structural analysis from colleges and universities, as well as from industry. The XCL specializes in samples that suffer from twinning, small size or solvent loss. Please contact us for questions concerning the submission procedure (download sample submission form).
Annually, we teach an X-ray crystallography class which covers theory and prepares students to carry out their own structural analyses. Students and postdocs with previous experience in X-ray crystallography may also become facility users. Policies: 1) Clients of our facility receive by email a full report file and a CIF (crystallographic information file) which is required by most journals. 2) All samples are retained by our facility for one month before disposal. Should a client wish a sample returned, he or she should request it with submission. Instrumentation:Bruker-AXS platform diffractometers with CCD area detectors and sealed-tube 3-KW X-ray generators. The single crystal instruments are controlled by PC computers and are equipped with low temperature devices. An Oxford Cryostream Cooler allows us to investigate samples in a temperature range between 80 and 300 K. Data are analyzed on Windows 2000 workstations loaded with the SHELXTL V6.10 crystallographic software package from Bruker-AXS for structure solution, refinement and graphical presentation. Site-wide licenses are available for other departmental computers. In addition, program suites WINGX and , the Cambridge Structural Database (CSD), and the Inorganic Crystal Structure Database (ICSD) are available for site users.
