High Resolution Magic Angle Spinning (HR-MAS) NMR is a technique to obtain high resolution NMR spectra in inhomogeneous, colloidal, or semi-solid samples which would yield broad unresolved spectra using routine solution-state NMR techniques. By spinning samples at the magic angle, anisotropic interactions within the sample are averaged, providing dramatically improved resolution. HR-MAS is frequently applied to hydrogels and other polymers, as well as biological tissues.
Our AVIIIS 600 MHz spectrometer is equipped with a 4mm HR-MAS probe, which includes a deuterium lock channel and magic angle gradient.
