Our Facility also offers data collection and structure determination to for-profit customers. Click this link for details about variable-temperature transmission-mode powder diffraction. With very careful sample preparation one can further reduce the amount of sample needed to approximately 1 cubic millimeter. Transmission-mode powder diffractomery is particularly interesting when only small amounts of sample are available, because one only needs to fill a tube with an inner diameter of 0.64 mm about 5 mm high, which corresponds to approximately 1.6 cubic millimeters of tightly packed sample. While the Chemistry Departments Diffraction Facility is primarily a single-crystal facility, we also offer transmission-mode (in capillaries) powder diffraction at temperatures from 100K to 500K. This service can be vital for pharmaceutically relevant molecules or natural compounds.

Thanks to our modern equipment, which is carefully maintained, and recent progress in methods and software development, we also offer determination of absolute configuration of chiral compounds from light-atom structures where oxygen is the heaviest element present (at least one oxygen for every 10 carbon / nitrogen atoms is recommended). Of course, our instruments cannot compete with a synchrotron, but our modern ImuS microfocus X-ray tubes compare favorably with (and, in terms of flux density, possibly outperform) all rotating anode generators currently present on MIT campus. That also incudes data collection on protein crystals. The Chemistry Departments X-Ray Diffraction Facility offers single-crystal data collection and structure determination services at the highest level of the art on all kinds of molecules, including inorganic, organic, organometallic and biological samples. Click this link for pictures of our diffraction equipment. Cu radiation is required to obtain anomalous signal from light-atom structures and is sometimes needed to obtain a good diffraction pattern from very small crystals. Mo radiation gives rise to higher resolution data and is the preferred wavelength for most routine samples. Data collection can be performed using Mo or Cu radiation, depending on the requirements of the project. These diffractometers are coupled to extraordinarily sensitive Bruker APEX and APEX2 CCD detectors that give rise to high-resolution data even on very small crystals (down to 10µm). The MIT X-ray diffraction facility is equipped with state-of-the-art and versatile Bruker diffracton equipment that allows collecting complete and highly redundant datasets in any given Laue class meeting or exceeding the International Union of Crystallography requirements for good data.
