The brand new Bruker 400MHz (9.4T) Dynamic Nuclear Polarization (DNP) NMR spectrometer is available for solid-state experiments.

DNP Features:

• 25 W gyrotron microwave source
• G-factor range from 2.0163777 to 1.9844550
• about 95 K operating temperatures
• Magic angle spinning up to 12.5 kHz
• ¹³C DNP-CPMAS NMR enhancements of 300-fold with proline and AMUPol

Available NMR probes:

•   3.2mm MAS DNP-NMR triple resonance broadband X/Y/H probe

               -- H channel: ¹H (400MHz) only

               -- X channel: 76 MHz -> 129 MHz (including ⁷⁷Se, ²⁹Si, ⁵⁵Mn, ⁷⁹Br, ¹³C, ²⁷Al, ²³Na, ⁷¹Ga, ¹¹B, etc.)

               -- Y channel: 28 MHz -> 71 MHz (including ²H, ¹⁵N, ¹⁴N, etc.)
