Magic Angle Spinning (MAS) Probes

The NMR Instituut, led by Prof. Ago Samoson, has been a chief innovator of MAS NMR probes for many years. Prof. Samoson has numerous publications and patents, which are reflected in the innovation of these leading edge probes. 

NMRi offers the highest speed and sensitivity, particularly important for the rapidly expanding field of bio-solids. NMRi offers a range of sample sizes which dictate the maximum spinning speed.

NMRi probes share many convenient features allowing even novice users to obtain excellent results
