The X-ray Spectrum of Monazite (PDF)

This research investigates the application of laser-induced breakdown spectroscopy (LIBS) and machine learning (ML) for detecting elemental composition of food, using rice as an example.

An interview with Charles Wilkins, the winner of the 2013 American Chemical Society Division of Analytical Chemistry Award in Chemical Instrumentation, sponsored by the Dow Chemical Company.

A new approach to analyzing bituminous coals was created using Fourier transform infrared spectroscopy.

With Pittcon 2025 officially beginning, here are some notable upcoming workshops based around the advancement of spectroscopy.

Spectroscopy recently sat down with Dr. Geraldine Monjardez and two of her coauthors, Dr. Christopher Zall and Dr. Jared Estevanes, to discuss their most recent study, which examined the crystal structure of ammonium nitrate (AN) following exposure to explosive events.

In 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.
