Services
Georgetown University researchers who intend to incorporate X-ray diffraction as a regular tool in their analytical toolbox are strongly encouraged to become fully trained instrument users. Georgetown researchers who do not intend to regularly use the X-ray facilities can simply contact Dr. Bertke to discuss experiments and submit samples. Researchers outside of Georgetown University should contact Dr. Bertke to discuss experimental needs and pricing.
