Crystal Structure Determination

Crystallographic analysis of X-ray diffraction data.

X-ray crystallography is used in many fields of chemistry, mineralogy and physics. Not only in the so-called crystalline state (ordered position of ions, atoms or molecules) but also in the amorphous and liquid states that do not have long-order periodicity.

Since I made my first steps in the powder diffraction community, I have been amazed by the many possibilities for collecting diffractograms. In this blog, I’ll describe how I learned about the advantages of transmission geometry over reflection geometry for specific samples.
In almost every powder diffractometer, the reflection geometry is being used: the detector is at the same side of the sample surface.
This geometry works very well for inorganic materials that can be prepared as flat samples with randomly oriented crystallites.
One of the disadvantages of reflection geometry is that it …

Recently passengers were forced to evacuate a flight at Barcelona airport after a passenger’s mobile phone, connected to an external lithium battery pack, burst into flames.
It is a situation like this that makes us once again realize how very dependent we all are on electricity. Just about everything we use is powered in one way or another. More and more mobile devices are used which get ever more powerful and combine various tasks in one single machine. With this increasing performance and consequently increasing energy consumption of mobile electronics, the requirements …

Detection of trace polymorphs, determination of amorphous content, and the study of the stability of active pharmaceutical ingredients (APIs) subjected to heat and humidity are some of the many applications where a modern powder X-ray diffraction (PXRD) system can add value to drug development.  Advances in beam conditioning and detector technology have led to greatly improved detection limits, resolution, and range of applications now possible. Today’s modern, laboratory-based PXRD instrumentation and advanced software can greatly assist pharmaceutical scientists in their quest to develop high quality, stable products and accelerate their …
