Sensitivity boost for solid-state NMR

As the market leader, Bruker introduces the world’s first commercially available solid-state dynamic nuclear polarization-enhanced NMR system (DNP-NMR)

Bruker’s 263, 395, 527 and 593 GHz DNP-NMR Spectrometers are the world’s first commercially available solid-state dynamic nuclear polarization (DNP-NMR) systems . All DNP-NMR spectrometers enable extended solid-state NMR experiments with unsurpassed sensitivity for exciting new applications in biomolecular research, material science, and pharmaceuticals. The Bruker DNP spectrometers have a proven record of performance over 35 systems installed worldwide. 

Signal enhancements range from 20 to a factor of 400, driven by microwave irradiation to transfer polarization from unpaired electron spins to nuclear spins. The unique high power gyrotron systems, delivering microwaves at 263 GHz, 395 GHz, 527 GHz and 593 GHz are robust, safe and easy-to-use, enabling long term DNP experiments without time limitations. A 263 GHz klystron is also available for DNP experiments at 400 MHz, delivering top-notch signal enhancements at a lower cost and with reduced infrastructure requirements.

DNP Boltzmann Polarization

DNP samples are prepared by adding a polarizing agent or exploiting a native radical on the sample of interest. Experiments are performed at a low temperature of ~100 K with continuous microwave irradiations and benefit from the innovative low-temperature MAS probe that enables sample polarization in-situ, directly at the NMR field.
