Introduction. Environmental regulations set the maximum permitted sulfur level in car fuels at 10 mg/kg. Several different X-ray fluorescence technology test methods are available for analyzing the sulfur concentration, for example, ASTM D4294 (EDXRF) and ASTM D2622 (WDXRF). The environmental Protection Agency (EPA) Tier 3 regulation introduced in 2017, is XRF technology independent, with the condition that the performance of the instrument meets the Tier 3 accuracy and precision requirements.. This application note shows that Epsilon 4 complies with the Tier 3 requirements in only five minutes measuring time. .

Visualizing structural changes in batteries using hard radiation and the GaliPIX3D detectorIn this data sheet, we present CT results obtained on alkaline batteries using an Empyrean diffractometer. . Zn – MnO2 alkaline batteries were investigated by computed tomography using an Empyrean multipurpose laboratory diffractometer in combination with hard X-radiation (Ag anode) and the GaliPIX3D detector. The differences between the charged and the discharged state can be clearly observed and are in agreement with results obtained at synchrotron radiation facilities..

Polyvinyl chloride (PVC) is a common polymer used in countless applications from pipes, to flooring, and electrical insulation. As one of the world’s most widely produced polymers, it is very much a commodity polymer where tight margins mean little room for detailed analysis. However, even in this case, high level analytical tools can be used to characterize the polymer for appropriate grading. For example, the glossiness of a PVC sample has a significant effect on its finish and grade, and for which applications it can be used. Applying appropriate characterization tools can help grade different PVC batches, assigning them to appropriate applications to maximize the value of high quality batches, saving lower grades for others.. In this application note, four PVC samples of known differences in glossiness were measured with both multi-detector GPC and rotational rheometry. The results both explain the differences in glossiness and the likely cause of those differences..

For virus development and production, it is important to know the virus concentration at different stages of the process, to optimize the clone used as well as the production yields. For example, instances such as clone screening, multiplicity of infection (MOI) optimization and adaptations of cell culture methods are instances when virus concentration, or virus titre as it is also commonly called, is of interest.. Dynamic light scattering (DLS) is often used in virus development, in a screening function to separate good and stable samples from those with contaminants or aggregates. With the new multi-angle DLS (MADLS) based particle concentration measurement in the Zetasizer Ultra, it is now possible to get both size and size distribution as well as particle concentration per population, within a few minutes.. In this application note, Allergan are kindly sharing data from their evaluation of the Zetasizer Ultra, examples of three adeno-associated virus (AAV) samples are shown. The concentration results are compared to results from capsid ELISA based virus titre assays. .
