Temperature controllers provide an inert atmosphere (N2) for the samples.
Samples are examined with a polarizing microscope; air-sensitive materials are prepared under an inert atmosphere.
Typical data collections, which take anywhere from 2 to 24 hours, are run at 100 K, with an optional range from 90 to 400 K.
The submitter receives via email a CIF (crystallographic information file) and full report file (PDF and DOC formats). CIFs are used for journal and database submissions and for structure manipulation by third party software like program Mercury. Report files contain pertinent information, like the conditions of the experiment, structure solution and refinement details, thermal ellipsoid plots, and tables bond lengths and angles, etc., in easily readable and printable formats.
Stereochemical information can be determined (see individual instrument details).
Twinned crystals, including non-merohedral ones, are routinely examined and successfully resolved at no additional cost.
On average only a few crystals are required to find an acceptable specimen; more is better, bigger is better.
Crystals are accepted dry or in mother liquor.
Samples are not returned unless the submitter requests it.
Completed structural determination:
University of Rochester research groups: $300.
External research groups from non-profit organizations: $300 + $50 staff support fee ($350 total).
Reserved two hour screening blocks:
All users: $75.
If during the two hour screening window it is decided that a full data collection is desired, the $75 fee is waived and the experiment evolves into a structural determination (see above).
