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.
