ASTM Standard D-6751 - Determination of Trace Elements in Biodiesel Fuel Using the Teledyne Leeman Lab’s Prodigy 7 ICP-OES
Biodiesel fuel is easily analyzed using the Prodigy7 ICP. The detection limit of Teledyne Leeman Lab’s Prodigy7 ICP-OES readily exceeds the requirements of the ASTM D-6751 Standard against which biodiesel must be measured. Samples are easily prepared by dilution with a suitable solvent. Sample spike recoveries and reference standards results indicate that the method is suitable for the analysis of biodiesel fuels and that matrix interferences are not an issue.
Applications of Micro X-Ray Fluorescence Spectroscopy in Food and Agricultural Products
January 25th 2025In recent years, advances in X-ray optics and detectors have enabled the commercialization of laboratory μXRF spectrometers with spot sizes of ~3 to 30 μm that are suitable for routine imaging of element localization, which was previously only available with scanning electron microscopy (SEM-EDS). This new technique opens a variety of new μXRF applications in the food and agricultural sciences, which have the potential to provide researchers with valuable data that can enhance food safety, improve product consistency, and refine our understanding of the mechanisms of elemental uptake and homeostasis in agricultural crops. This month’s column takes a more detailed look at some of those application areas.
