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.

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.
