X-ray
Crystallography - Dr. Fusen Han |

A
brand new small molecule crystallographic instrument was installed in Nov
2003. The "Smart Apex CCD Area Detector System" developed and
made by Bruker Axs Inc. is the new generation of the x-ray diffraction equipment.
It is equipped with a SMART APEX CCD Area Detector, a Fine Focus sealed
X-ray tube using Mo-K(alpha) radiation, a MonoCap collimator for increased
X-ray beam intensity, and an Oxford Cryostream device to allow data collection
at temperatures as low as -160 C. Also available is the Enraf-Nonius CAD-4
Turbo Diffractometer |

|
| |
The
main advantages of this new system are: |
| |
|
|
|
•
|
Fast
data collection: An entire data set can be collected within 6 hours. |
| • |
Smaller
crystal samples: Monocap collimator increases x-ray intensity up to six
times. |
| • |
More
powerful software: From data collection to structure solution, the instrument
is equipped with a new set of powerful computer software for dealing with
more difficult crystal samples and structures. |
| • |
Very
easy to operate: GUI interface makes it possible for non-crystallographers
to use it for routine structure determinations. |
| • |
Low
temperature: Can collect data at -120 C, which stabilizes the sample during
the experiment and provides higher quality data. |
