600 MHz 89 mm MAS DNP System

600 MHz 89 mm MAS DNP System 600 MHz 89 mm MAS DNP System

This instrument is located at the MagLab's Tallahassee headquarters.

The increased sensitivity of MAS DNP allows high resolution solid state NMR spectroscopy to be used for many previously inaccessible systems. Our Bruker DNP spectrometer utilizes a 394 GHz gyrotron to produce a strong microwave field to enhance NMR polarization.
