X-ray Crystallography Facility
The LSU Department of Chemistry X-ray Crystallography Facility occupies 450 sq ft on the 6th floor of Choppin Hall.
The Facility Manager is Dr. Frank R. Fronczek (ffroncz@lsu.edu).
Facility Equipment:
- A Bruker D8 Venture DUO diffractometer equipped with two X-ray sources and a Photon III C14 detector. The ImuS microfocus X-ray sources are Cu, which is particularly well suited for the study of small, weakly scattering crystals and for absolute configuration determination of chiral organics and also Ag, which is good for high resolution data on highly absorbing materials. The diffractometer is also equipped with an Oxford Cryostream 1000 cryostat capable of maintaining temperatures in the range 90-400K. Most data are collected at about 100K.
- A Bruker Kappa Apex-II diffractometer equipped with a sealed-tube Mo X-ray source and Triumph focusing monochromator. This instrument is equipped with an Oxford Cryostream model 700 cryostat.
- Four Windows 10 computers with complete suites of crystallographic software. Software is the Bruker Apex5 suite, which includes diffractometer-control routines, SHELXT and SHELXL structure solution and refinement programs, and graphics interfaces. The department also has a site license for the Cambridge Structural Database and associated software for searching and analyzing literature structures.
- A Zeiss 2000-C stereo zoom polarizing microscope for sample manipulation and crystal mounting. It is equipped with a digital camera and a TV display, which allows others to observe what is seen through the microscope and photography of samples.
