Raman microscopy is one of the techniques of choice for investigating heterogeneous systems on the micrometer scale. Part I of this two-part article series reviews the issues that must be considered to interpret confocal Raman data correctly.
High-Speed Laser MS for Precise, Prep-Free Environmental Particle Tracking
April 21st 2025Scientists at Oak Ridge National Laboratory have demonstrated that a fast, laser-based mass spectrometry method—LA-ICP-TOF-MS—can accurately detect and identify airborne environmental particles, including toxic metal particles like ruthenium, without the need for complex sample preparation. The work offers a breakthrough in rapid, high-resolution analysis of environmental pollutants.
