High-Field Field-Cycler (HFFC)

Our High-Field Field-Cycler (HFFC) is a rapid sample shuttler adapted on your high-field NMR spectrometer.

The compact sample transportation devices, “High-Field Field-Cyclers”, were installed in many worldwide commercial spectrometers. Our device provides high-precise positioning and stability during high-speed shuttling and are compatible with commercial high-field standard bore NMR spectrometers with commercial probe heads, including a cryogenically cooled NMR probes.
Various aspects of relaxation studies, such as relaxivity measurements allow to obtain detailed information on protein dynamics and contrast agents for magnetic resonance imaging at the atomic resolution. Despite relaxation studies, our newly developed add-on module (see also Field-Cycling Illuminator) combined with our High-Field Field-Cycler can perform field-dependent photo-related experiments in solutions, for instance photochemical induced nuclear polarization (photo-CIDNP).

The sample is shuttling up and down with acceleration 131.25m/s2. The shown video is the area of the rail approximate to the probe head.

Key Features

  • High speed: The shuttle can travel 100cm in minima 80ms
  • High stability
    • The shuttle motion follows the linear motion in constant acceleration.
    • Tens ms equalibrium time after a high-speed shuttling action.
    • Programable acceleration according to different sensitivities of samples.
  • User-friendly sample loading and packing
    • Easy operation on sample preparation:
      The system uses the regular NMR tube, no special size or style of NMR tube is required. One can finish sample packing in few minutes.
  • User-friendly software:
    • shuttling positions are programable
    • computer-aid sample loading
    • programable shuttling profile
  • The shuttle rail is designed for nearly all existing commercially availible spectrometers
    • The device is installed in the spectrometer with small occupied space.
    • The system is adaptable for conventional probeheads, including cryoprobes. (No special requirement)
    • The device also can function as regular sample lifting for other experimental purposes.
