X-ray Diffraction Laboratory


Welcome

All qualified Texas A & M University employees and visiting scholars may use the facilities provided they have completed the required X-ray safety and instrument training and have the approval of the Department of Chemistry and their supervisor.

To get started you should know what you require from X-ray Diffraction (powder or single crystal) and what you have (a crystal, powder, solid etc.) to analyze.

To answer some of these questions start with the FAQ section of this web site.

You may want to use X-ray Diffraction if

  1. You want a molecular or extended structure and you have a large (> 100 micron) single crystal
  2. You have a crystalline powder and you want to determine its powder pattern
  3. You have a solid that is semi-crystalline and you want to characterize it

You may want to use Small Angle X-ray Scattering (SAXS) if

  1. You have a solid or liquid containing particles no larger than 100 nanometers.
  2. You have a Zeolite or porous structure
