Design and performances of a Tabletop DNP Polarizer : Towards recyclable hyperpolarization

Could the sensitivity be boosted by 100 in 2D NMR and acquisition time greatly reduced? Seems a real challenge, yet not impossible 🤓 Please enjoy our teaser 🎥 that introduces the HypFlow project we have at #HMRLab 🙂 🇫🇷@Sami_HMRlab @quentinchapp pic.twitter.com/7ey1zCLHh8

Dissolution Dynamic Nuclear Polarization provides a 10’000-fold gain in sensitivity but is incompatible with multi-scan experiments. Our ambition is to turn d-DNP into a new version widely compatible with NMR spectroscopy by replenishing hyperpolarization with a compact instrumentation for melt-DNP. Here I present the performances of the 1T polarizer using water-soluble radicals and porous matrices.
