Electron diffraction (known also as ED, 3D ED or microED) performing nano-crystallography on crystals smaller than 1 µm is increasingly gaining momentum in science and industry. Complementary to neutron-, powder-, and single-crystal X-ray diffraction, the disruptive technology of electron diffraction opens up fascinating new perspectives for a wide variety of compounds in the fields of chemical, pharmaceutical, and advanced materials research.
The recent introduction of dedicated instrumentation to perform ED experiments is a key aspect of the continued growth and success of this technology. ELDICO Scientific presents the electron diffractometer ED-1, a smart combination of a 5-axis nanometer-precise goniometer, a large sample chamber, radically simplified electron optics, and an ultra-high-speed hybrid-pixel Dectris Quadro® camera for diffraction data acquisition.
Several examples of data collected on ELDICO ED-1 are showcased to demonstrate the potential and advantages of a dedicated electron diffractometer, covering selected applications and challenges of electron diffraction: 1) polymorphism and absolute structure of pharmaceutical compounds, 2) crystal mapping and extrapolation to powder XRD, and 3) structure elucidation of energy storage materials.
