Atomic Spectroscopy

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.

Brines from desalination plants are increasingly being seen as a source of valuable elements, such as lithium, rubidium, and cesium. We show how ICP-OES can be used to measure the concentrations of such elements in brines to assess the economic feasibility of their recovery.

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.

The fast data acquisition and minimal sample preparation of handheld LIBS devices make them very useful for geochemical mapping, resource prospecting, sample selection, and hazard identification.

Denise M. Mitrano is an Assistant Professor of Environmental Chemistry of Anthropogenic Materials at ETH Zurich in the Department of Environmental Systems Science. Her research is directed to understanding the impact and interaction of nanoparticles in the environment using atomic spectroscopy techniques, such as inductively coupled plasma–mass spectrometry (ICP-MS) and single-particle ICP-MS (sp-ICP-MS). She is the winner of the 2022 Emerging Leader in Atomic Spectroscopy Award. Chosen by an independent committee, the Emerging Leader in Atomic Spectroscopy Award recognizes the achievements and aspirations of a talented young atomic spectroscopist who has made strides early in his or her career toward the advancement of atomic spectroscopy techniques and applications. We recently interviewed Mitrano about her work.

Denise M. Mitrano of ETH Zurich, the 2022 winner of the Emerging Leader in Atomic Spectroscopy Award, is applying ICP-MS and single-particle ICP-MS to elucidate the transport and impact of nanomaterials and nano- and microplastics.

How can you assess real-world detection capability of an ICP-MS system?

In this study, a methodical qualitative and quantitative analysis of H-Classic publications that have made key contributions and identify intensive mainstream research areas in atomic spectroscopy is presented.

The way the analytical signal is managed in ICP-MS has a direct impact on the results generated. In this first of a two-part series, we explain the fundamental principles of a scanning quadrupole and how measurement protocols can be optimized based on data quality objectives.

Attaining accurate quantitative results in atomic spectroscopy requires proper calibration, especially when measuring low-level concentrations near detection limits. This tutorial explains key concepts of calibration, illustrated with specific examples.

A recent investigation found dangerous levels of heavy metals in commercial baby foods. Tighter scrutiny and regulations are needed.

L. Robert Baker, the 2021 Emerging Leader in Atomic Spectroscopy, applies ultra- fast, time-resolved X-ray spectroscopy to explore charge transfer at surfaces, to understand electron transfer, energy conversion, electrochemistry, and catalysis.

EPA Method 200.8 and the Lead and Copper Rule Revisions don’t allow use of modern ICP-MS technology with a collision cell. Instead, correction equations can be used to compensate for polyatomic interferences.

This article provides a convenient summary of portable and handheld spectroscopy techniques, outlining the most prominent types of compact instruments for both atomic and molecular spectroscopy.

This method detects elements intrinsically present in cells, and because sc-ICP-TOF-MS measures a full mass spectrum, no analytes are missed.

Nebulizer selection is a critical but often overlooked aspect of inductively coupled plasma–optical emission spectroscopy (ICP-OES) analyses. There are many different nebulizers available for ICP-OES, and choosing the optimal one can be confusing and difficult. To achieve peak performance from your ICP, it is essential to choose the proper nebulizer based on your sample types in addition to any necessary accessories to maintain long-term performance. In this study, we compare the performance of Glass Expansion’s most popular concentric nebulizer designs for ICP-OES applications as well as a parallel-path nebulizer from another vendor, providing a complete selection guide based on performance and design.

For a number of elements, spectroscopic interferences can have a significant impact on the ability to achieve low detection limits in ICP-MS. We investigate the mechanisms in multi-quadrupole ICP-MS that are designed to remove these interferences.

Material identification, also called positive material identification (PMI), is used to analyze and identify materials for quality assurance and quality control to verify proper alloy or material is being used.

There is no doubt that funding for basic science in analytical atomic spectroscopy has waned over the years, and, in reality, barely exists today.

Great interest has recently aroused in the study of the dysregulation of chemical elements within tissues. Information about the distribution of elements in biological tissues can contribute to a more complete medical diagnosis, and can guide therapeutic procedures for many pathologies.
