Single Crystal X-ray Diffraction
With funding from the National Science Foundation, the Department of Chemistry installed a state-of-the-art SMART APEX2 platform X-ray diffractometer from Bruker Advanced X-ray Solutions in November 2005. The instrument is equipped with a MonoCap X-ray waveguide that increases the collimated X-ray intensity by a factor of 2.5, an APEX II charge-couple device (CCD) detector with ten-fold better sensitivity than first generation CCD's and an Oxford liquid nitrogen cryostream. These features make the instrument useful for a large variety of samples, including tiny, weakly diffracting and air-sensitive materials.
Science faculty members in the Hudson Valley who are interested in using the new instrument to obtain X-ray crystal structures in support of their research should contact Professor Tanski.
