Characterization of nanoparticles (NPs), including samples containing different sized NPs is described using ICP-MS. New integrated data analysis software is capable of quickly and automatically performing the complex calculations required for the analysis of single particles, while permitting simple, visual optimization and validation of results. The method provides a combination of particle size distribution and sample concentration information that is generally not available with other techniques.

sCMOS vs CCD: Advancing High-Speed CARS Spectroscopy
July 14th 2025A new comparative study shows that scientific CMOS (sCMOS) cameras could rival traditional CCD detectors in certain Raman CARS spectroscopy applications, offering faster readout and dynamic range despite slightly higher noise levels.
How Analytical Chemists Are Navigating DOGE-Driven Funding Cuts
July 14th 2025DOGE-related federal funding cuts have sharply reduced salaries, lab budgets, and graduate support in academia. Researchers view the politically driven shifts in priorities as part of recurring systemic issues in U.S. science funding during administrative transitions. The impact on Federal laboratories has varied, with some seeing immediate effects and others experiencing more gradual effects. In general, there is rising uncertainty over future appropriations. Sustainable recovery may require structural reforms, leaner administration, and stronger industry-academia collaboration. New commentary underscores similar challenges, noting scaled-back graduate admissions, spending freezes, and a pervasive sense of overwhelming stress among faculty, students, and staff. This article addresses these issues for the analytical chemistry community.
