Field-cycling NMR goes beyond conventional NMR by dynamically varying the magnetic field during an experiment. This unlocks access to relaxation dispersion profiles, molecular dynamics, and field-dependent interactions — measurements simply not possible at a fixed field. FCNMR's instruments bring this capability directly to high-field spectrometers already in your lab.
HFFC-NMR is a high-resolution relaxometer built around fast sample shuttling across a wide range of magnetic fields, all within a single experiment on your existing high-field magnet. The result is a complete field-dependent NMR relaxation profile (NMRD) with the chemical shift resolution your research demands. Key applications include MRI contrast agent relaxivity characterization, protein dynamics, and soft matter research, with no changes to your high-field infrastructure.
In-situ illumination enables light-driven reactions to be observed directly inside the NMR tube, no transfer, no delay. Photo-CIDNP exploits spin polarization changes induced by light to detect aromatic amino acids and folded proteins at concentrations as low as the nano-molar range. Combined with field-cycling, it opens a unique window into photochemical and biological dynamics.
