Oxford Diffraction Nova X-ray Diffraction System
The science division operates an X-ray diffraction system for use in classes and student-faculty research. This is an Oxford Diffraction Nova system, including sealed-tube microfocus X-ray source, CCD detector (Onyx), and sample temperature controller (Cryojet).
Sample Chamber Detail
The instrument is employed for X-ray diffraction analysis of solid and liquid samples. Three classes of experiments are typically carried out:
- powder diffraction
- small molecule structure determination
- macromolecular structure determination
The X-ray Diffraction Laboratory also includes the following:
Two Leica stereomicroscopes for sample mounting, including the M205C (above). This scope has a 20.5:1 zoom, and a ccd camera which permits simultaneous stereo imaging under the microscope and viewing on the computer screen with the camera. This is very useful for demonstrating mounting techniques.
The X-ray Diffraction Lab is currently used for courses in Geology, Physics and BBMB, and for research projects by students and faculty.
We have developed some X-ray diffraction laboratory classroom activities.
The instrument was purchased with a 2007 award from the National Science Foundation.
