Specifications

  • 6.7 T persistent, dry magnet with low drift rate and fixed leads (Cryogenic Ltd).
  • Re-condensing, variable temperature insert with base temperature of <1.4 K; temperature controllable to 300 K continuously.
  • No liquid cryogens needed. Cooling provided by Sumitomo SRP-082B cold head and F-70H compressor.
  • Microwave frequency 188 ± 2.0 GHz / frequency modulation / pulse modulation / gating / 100 mW / 20 dB attenuation.
  • NMR probe tuned for 13C (72 MHz). NMR coil tuned remotely to provide flexibility for other nuclei.
  • Solid-state NMR spectrometer for measuring polarization build-up.
    Based on RS2D Cameleon 4, T/R switch, 300 W amplifier (5-310 MHz) and SPINit software.
  • Fluid path optimized for dissolution of pre-clinical and in vitro samples.
  • Fully automated software control.
  • Polarizer foot print 1.42 x 0.80 m2, height 1.85 m. Minimum floor space required for operation and service 4 m2. Weight: SpinAligner 400 kg; compressor 100 kg

Acceptance test

  • 2 mL of 80 mM [1-13C]pyruvate with liquid state polarization >50% at time of dissolution.

Installation requirements

  • Compressor requires cooling water and 3-phase electricity.
  • SpinAligner requires 240 V / 10 A (50 Hz or 60 Hz)
  • Helium gas 5.0 (50 L/200 bar cylinder or equivalent).
  • Compressed air >5 bar.
