395 GHz/600 MHz Bruker Avance III DNP NMR

The 395 GHz/600 MHz Dynamic Nuclear Polarization (DNP) NMR spectrometer provides unparalleled sensitivity for membrane protein and other solid-state NMR samples. Upon addition of a stable radical species into the sample, microwaves are used to transfer polarization from the radical’s unpaired electron to the nuclei of the sample of interest, providing a 30- to 40-fold boost in signal intensity. This in turn provides a time savings of 900- to 1600-fold over conventional NMR spectroscopy. 

The low-temperature 3.2mm Magic Angle Spinning solid state NMR probe may also be used for conventional NMR studies at temperatures as cold as 100 K.
