Selective laser sintering (SLS) is an additive manufacturing technique that uses a laser to selectively sinter powdered material (typically nylon or polyamide) to create a solid 3-dimensional structure. SLS has the potential to produce serial parts with high quality and high mechanical properties. Although the technique has been noted to have high potential for many years, there remain some challenges facing this approach.

Fluorescence is commonly a problem in mineralogical phases like Hematite- Eskolaite, because these minerals contain the strongly fluorescing Cr and Fe ions. This data sheet shows how the 1Der detector excludes both Cr and Fe fluorescence. Empyrean’s unique optical configuration provides truly clean data leading to an excellent Rietveld refinement and resulting in an accurate crystal structure determination of this natural mineral. For X-ray diffraction (XRD) measurements on the Empyrean system, it is beneficial to be able to choose an X-ray tube to suit the requirements of a material. Standard Empyrean tubes offer a choice of Cr, Mn, Fe, Co, Cu, Mo and Ag, and other anode emission energies can be provided on request. Cu is the most commonly used anode and the Cu Kα emission peak is the most commonly used energy for diffraction experiments. In an X-ray diffraction experiment, the optics and the detector are together tuned to the narrow energy window required by the experiment. The 1Der strip detector can be automatically tuned to provide a narrow energy window around any chosen diffraction energy. This provides full flexibility across the whole range of Empyrean 1D applications. All elements fluoresce when irradiated with a certain X-ray energy. In a diffraction measurement, fluorescence from some elements can give rise to unwanted background intensity in a diffraction pattern. A high background reduces the possibility of identifying the low intensity peaks that often provide the final clues in a Rietveld crystal structure refinement. Figure 1 illustrates the elements that emit the greatest fluorescence interference in a diffraction measurement using a Cu X-ray tube. There are various strategies for excluding fluorescence interference and, in this datasheet, we show how the 1Der detector address the double challenge of fluorescence from both Cr and Fe elements.

This data sheet shows how the Empyrean X-ray diffractometer with 1Der strip detector is successfully employed to measure crystalline phase changes during battery cycling. The Empyrean equipped with hard radiation and the 1Der detector offers you a versatile approach to crystallographic measurements in battery research and production. The operando (operating) technique enables real-time X-ray diffraction (XRD) characterization of the crystalline phases in battery electrodes. The structural evolution of phases can be tracked during the charge-discharge cycling of the battery. The ion-exchange reaction can be studied under varying operating conditions for a deeper understanding of battery performance, stability and lifetime. Pouch cells are often used in battery technology research and are increasingly being used for integration into e.g. automotive applications, due to the benefits of cheap and versatile production. Pouch cells can be fabricated with varying thicknesses, sizes and shapes. Used cells are easy to store and recycle. On the Empyrean XRD system, pouch cells are easy to study in transmission geometry and their flat, often rectangular shape also allows for mapping of measurements at different positions across the battery cell. The 1Der detector is a truly versatile option for this set up, enabling operando battery measurements alongside other more conventional experiments.

Gene therapy is an area of rapid growth within the biopharmaceutical sector which uses genes to treat or prevent a disorder. The vectors which are used in gene therapy can be viral, non-viral and engineered vectors. In this work, we are focusing on a single viral vector used in gene therapy, recombinant adeno associated viruses (rAAV). In this application note rapid, accurate, and robust quantitative measurements of viral titer and full capsid content for AAV samples will be described. This study will demonstrate the capabilities of OMNISEC and ZS Ultra for analyses of rAAV5 samples at different levels of genome loading and sample heterogeneity.
