The MonoCap™ collimator is an assembly of a single glass tube mounted into a metal holder. The system uses a horizontal-oriented D8 3circle goniometer base with 2-theta, omega and phi drivesand a fixed chi stage with an angle of 54.74º.Ī monocap collimator of 0.5 mm in diameter is used. The diffractometer is equipped with a CCD based Apex2 detector cooled to -55 ✬ using graphite 24monochromated Mo-K αradiation from a sealed fine-focus ceramic tube X-ray tube and a K780 X-ray generator. Contact InformationĮmail: X-ray crystallography facility is equipped with a state-of-the-art Smart Apex2 D85 diffractometer. The data sets will be collected remotely and processed in-house. Note: Crystals, which cannot be measured on this instrument because they are too small, can be sent to the Canadian Light source in Saskatoon, SK. The facility is used by departmental members, but is also available for academic users from other departments within and other academic and industrial institutions outside Queen’s University. The X-ray Crystallography Facility as part of the Department of Chemistry provides single crystal X-ray (for small molecules) for Chemistry, Material Sciences etc. Queen's University Faculty and Staff LiaisonsĬrystallography is the science of the arrangement of atoms in molecules and of the arrangement of molecules with respect to each other:Ĭrystallography borders, naturally, on pure physics, chemistry, biology, mineralogy, technology and also on mathematics, but is distinguished by being concerned with the methods and results of investigating the arrangement of atoms in matter, particularly when that arrangement has regular features.2018-2023 Strategic Plan of the Department.Online Continuing and Distance Studies Courses in Chemistry.
