Single Crystal vs Powder diffraction (6 of 6)
Tetracycline structures obtained from microcrystal - single crystal diffraction : synchrotron X-rays
- a powder can be a collection of very small single crystals
- 10x20x30 micron crystal (Clegg and Teat)
- Beamline 9.8 at Daresbury lab: Bruker Smart CCD
- http://srs.dl.ac.uk/xrd/9.8/
- Routine structure solution - including hydrogens found from the map
- Solved at the press of a button as the data was being collected. (few hours data collection)
- When in doubt - get a single crystal!!
