A recent study conducted in the Journal of Food Composition and Analysis examined the concentrations of ten metals in 52 commercially available wet and dry cat food samples, assessing their compliance with U.S. and European pet food safety standards. The lead author of this study, Lucy Semerjian, recently sat down with Spectroscopy to discuss the findings of her study.
A new study published in the Journal of Food Composition and Analysis by researchers at the University of Sharjah reveals that while most cat foods sold in Sharjah meet international safety standards, some contain elevated metal levels, prompting calls for stricter regulation and quality control to protect pet health.

ICP-OES can accurately measure the elemental ratios necessary to optimize battery performance and improve recycling efforts so that battery recoveries are optimized. The authors explore how ICP-OES can help manufacturers meet the increasing performance demands required for lithium-ion batteries.
Glow discharge (GD) spectroscopy is a well-established method in the elemental analysis of metals, coatings, and surface-modified materials.
Using internal standards is a common technique to correct for variations in sample matrices and the effect this has on analyte intensities. There are several basic criteria to be considered when using internal standards: selection of appropriate internal standards, the concentration added to the solutions analyzed, setting up in the correct view (axial vs. radial), how to introduce the internal standard to the solutions to be analyzed, and evaluating the resulting data. Each of these topics are considered and suggestions presented.
A team of researchers has conducted a successful round-robin test using total reflection X-ray fluorescence (TXRF) to analyze the elemental composition of rat tissue samples. The preliminary results demonstrate the effectiveness of TXRF in accurately determining the elemental composition of mammalian tissue.
