The Hitachi NanoFrontier is the first commercial LCMS system that combines the unparalleled separation of NanoLC with the high sensitivity of a Linear Ion Trap and the high performance of a Time-of-Flight mass analyzer. This unique hybrid design allows for operation in LIT mode for MSn (CID and ECD) or Q-TOF mode for MS/MS. The new and improved NanoFrontier eLD provides increased performance (sensitivity, resolution, and dynamic range) and a host of tools for the analysis and data processing of small and large biomolecules.
