Meetings and Consultations by Appointments onlyДЄcknowledgments: Users who publish papers including data collected on the Bruker SMART APEX I system should include the following statement: We would like to acknowledge the National ScienceFoundation (CHE-0116041) and the Ohio Board of Regents for funds used to purchase the Bruker-Nonius Apex CCD X-ray diffractometer used in this research. Recrystallization for optimal data analysis The diffractometer is equipped with a Oxford Cryosystem liquid nitrogen cooling for measurements at low temperature. The detector is a very sensitive Apex II CCD detector. It is equipped with a sealed X-ray tube (Mo radiation) and a Triumph monochromator to increase the intensity. Consultation for the best approaches of generating good diffraction crystals for data collection The Bruker Kappa Apex II diffractometer was installed in 2010.Collecting, and mounting of water, temperature, air, and light sensitive crystals.Data Collection, processing and analysis, including graphical presentations of structures.Our instrument is a Bruker Apex II Duo system with co-mounted Mo and Cu microfocus radiation sources.

The combination of the sensitive APEX II detector and strong source means that very small crystals can be examined and publishable structures obtained.В A Kryoflex X-ray generator with a Cu sealed tube running routinely at 1.6 kW (40 kV, 40 mA) of power output provides the X-ray radiation.The X-ray Center at The University of Akron is a state of the art facility capable of collecting high quality X-ray diffraction data on both small molecule and macromolecular crystalline samples. The larger anomalous signal also allows the determination of absolute configuration ofchiral light atom molecules. The Cu radiation provides a substantial increase (4-5 fold) in intensity for experiments on smaller crystals. Thus desolvation processes and temperature dependent phase changes may be monitored during the diffraction experiment. Charge balance necessitates interstitial alkali. General formula A j MII kMвЂ™ III(CN) 6 l В·nH 2 O MII and MвЂ™II determine the identity of the analogue, referred to as MMвЂ™- PBA. raw files to be handled in other software. However, the sample temperature may be varied between -173 вњ¬ and 123 вњ¬. Images are combined using the Pilot portion of APEX II, and then integrated. The samples are usually cooled to -163 вњ¬ by an Oxford Cryostream improving the high angle diffraction and reducing thermal noise from the sample. A Kryoflex X-ray generator with a Mo sealed tube running routinely at 1.6 kW (45 kV, 35 mA) of power output provides the X-ray radiation. Poorly diffracting and various types of twinned crystals can also be examined successfully. The Xray lab also has two single crystal Bruker APEX II CCD diffractometers.
