PennChemistry: X-Ray Diffraction Facility

Page header image


The small molecule facility consists of two Bruker instruments: an APEXII-DUO CCD diffractometer and a D8QUEST-CMOS diffractometer. Each machine is equipped with an Oxford CryoSystem low temperature device which enables routine data collections at 100K. The APEXII has both molybdenum and copper X-ray sources (the Cu source can be used to determine the absolute structures of light atom compounds - no atom larger than F). Data collection on both machines is very efficient and it is routine to collect one or two complete datasets on each machine in a 24-hour day.


The X-ray Facility is staffed by Dr. Patrick Carroll (Director) and Dr. Michael R. Gau (Staff Crystallographer).
