21 Tesla FT-ICR MS (123 mm bore diameter)

21 tesla FT-ICR MS. 21 tesla FT-ICR MS.

This new tool, featuring a magnet built by the Bruker Corporation and installed in 2014, represents the world’s highest field, persistent, superconducting magnet suitable for FT-ICR mass spectrometry.

The 21 T magnet design offers a 123-mm room temperature horizontal bore, with fringe field profiles and room temperature bore access optimized for FT-ICR MS. It includes many design features pioneered by Bruker, including operation at ~2 Kelvin by use of Bruker’s unique UltraStabilized™ sub-cooling technology, the UltraShield™ technology to reduce stray fields, as well as novel active magnet refrigeration technology that virtually eliminates cryogen refills and user maintenance of the magnet. In addition to FTMS, the 21 T magnet is also suitable for ultra-high field preclinical MRI for highest sensitivity and resolution in mouse neuroimaging. Read press release.
