Recently, at the 2022 SciX conference in Covington, Kentucky, Beatriz Fernandez, who is an Associate Professor at the University of Oviedo in Spain, presented, as part of the Technical Program, a discussion regarding the determination of proteins in single cells by ICP-MS using metal nanoclusters as labels of specific recognition reactions. Fernandez spoke to Spectroscopy about her presentation.
By using green synthesized AgNPs modified by chitosan and organic acid, a simple, cost-effective, and highly selective onsite colorimetric detection method for Pd2+ and Hg2+ ions was developed.
Some macrofungal species are known for their ability to accumulate high concentrations of mercury in their fruit bodies. A recent paper by Simone Braeuer and colleagues of the University of Graz (Austria) and Ghent University (Belgium) discusses an efficient method developed for quantitative mapping of mercury and selenium in mushroom fruit bodies via laser ablation coupled to inductively coupled plasma–mass spectrometry with excellent limits of detection and high spatial resolution (down to 5 µm). Braeuer spoke to Spectroscopy about this paper.
Lithium-based batteries are key for moving away from the combustion of fossil fuels at the point of use. ICP-OES and ICP-MS methods can measure trace-element impurities that may affect battery performance.
ICP-MS is increasingly being used to analyze complex matrices, but an ICP-MS instrument optimized for the highest sensitivity may not have the sufficient matrix tolerance to analyze high-salt samples. We describe a method to optimize plasma robustness and interference control for accurate, routine analysis of critical trace elements in undiluted seawater.
This tutorial explains the most critical components of the sample introduction system of modern ICP-optical emission spectroscopy (OES) and ICP-mass spectrometry (MS) instruments, providing analysts with a guide for initial configuration settings and recommended maintenance intervals for reliable daily operation.
Inductively coupled plasma mass spectrometry (ICP-MS) instruments can perform low-level elemental analysis in a wide range of sample types, from high-purity chemicals to high matrix digests. But achieving consistently low detection limits requires good control of elemental contamination, as well as spectral interferences. A clean working area, careful selection of reagents, and good sample handling techniques are key to successful trace and ultratrace elemental analysis. In this article, we provide five practical tips for controlling contaminants and minimizing detection limits.
In this study, X-ray fluorescence (XRF) spectroscopy was used to analyze heavy metals in five traditional Mongolian medicines, and the results were compared to those obtained using ICP-MS.

Tutorial
How to create trouble-free sample preparation workflow for elemental analysis.
A tutorial and spreadsheet for the validation and bottom-up uncertainty evaluation of quantifications performed by instrumental methods of analysis based on linear weighted calibrations were presented by Ricardo J.N. Bettencourt da Silva of the University of Lisbon in Lisbon, Portugal, and colleagues. This software tool was successfully applied to the determination of the mass concentration of Cd, Pb, As, Hg, Co, V, and Ni in a nasal spray by ICP-MS after samples dilution and acidification. Bettencourt da Silva spoke to Spectroscopy about applying this software tool and the implications for a better understanding of quantitative analytical results.
