Terephthalic acid (TPA) and purified terephthalic acid (PTA) are precursors in the making of polyester PET for polyester films, bottle resin, textile fabrics, and specialty chemicals. During production and use of TPA and PTA, the catalysts Co, Br and Mn must be closely monitored to ensure optimum product quality. Rigaku EDXRF Application Note #1539 describes the analysis of concentrations of Co, Br and Mn in TPA and PTA solutions and highlights the performance of the Rigaku NEX OL on-line EDXRF process analyzer.
The 2025 Emerging Leader in Atomic Spectroscopy Award
February 15th 2025Benjamin T. Manard has won the 2025 Emerging Leader in Atomic Spectroscopy Award for his pioneering research in nuclear material characterization and isotope ratio analysis, with expertise in advanced atomic spectrometry techniques such as inductively coupled plasma optical emission spectroscopy (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), and laser ablation.
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.
