There is growing concern about the unknown effects that nanoparticles may have on the environment, especially in drinking water and plants. Single-particle inductively coupled plasma–mass spectrometry (SP-ICP-MS) is emerging as a useful technique for analyzing nanoparticles and their presence in environmental and biological systems. Honglan Shi, a chemistry professor at Missouri University of Science and Technology, and her research group have been using SP-ICP-MS to investigate nanoparticles in drinking water and plant uptake. She recently spoke to Spectroscopy about this work.

The single-particle analytical technique can quantitate the difference between ionic and particulate signals, measure the particle concentration (particles per milliliter), and determine the particle size, size distribution, particle agglomeration, and dissolution. As a result, ICP-MS is a key analytical technique in assessing the fate, behavior, and distribution of nanomaterials in the environment.

The accurate determination of protein concentration is a challenge for biopharmaceutical companies when no reference standard is available. This isotope dilution ICP-MS/MS method based on sulfur determination is fast and allows for very accurate determination of a single protein in solution after microwave digestion. The method is tolerant of most matrices used for therapeutic protein formulations and is widely applicable.

Special Issues
In this study, red and white wines were investigated using an ICP-MS method and 14 different elements were quantified simultaneously: arsenic, cadmium, cesium, copper, chromium, vanadium, iron, manganese, nickel, lead, selenium, tin, thallium, and zinc. The developed method is highly accurate, regardless of element concentration.
