LC–MS system
The Orbitrap Fusion Tribrid LC–MS system from Thermo Fisher Scientific combines quadrupole, Orbitrap, and linear ion-trap mass analyzers and is designed for the analysis of complex biological samples. According to the company, users can choose between fragmentation modes at any stage of MSn analysis and unknowns in small-molecule experiments can be identified conclusively as they are encountered.

Rapid, Portable Mid-Infrared Spectroscopy Identifies Aflatoxins in Peanuts
March 10th 2025Researchers have developed a portable mid-infrared (IR) spectroscopic method combined with chemometric analysis to rapidly and non-destructively detect aflatoxin contamination in Aspergillus-infected peanuts. This approach offers a field-deployable alternative to traditional wet chemistry methods, with high sensitivity and specificity in identifying toxic metabolites such as aflatoxins.
A New Radiation: C.V. Raman and the Dawn of Quantum Spectroscopy, Part II
March 10th 2025In this Icons of Spectroscopy column, Executive Editor Jerome Workman Jr. delves into Part II of the Raman Effect, discovered by C. V. Raman, a physicist whose major contributions to vibrational spectroscopy have helped shape the field and advance one of the most important quantum-based spectroscopy tools of recent generations.
