Magic Angle Spinning | MAS Technology

Fusing Magic Angle Spinning (MAS) technology with the MR Microscopy gradient technology enables to acquire images and localized spectra of semi-solid objects due to the combination of reduced signal linewidth with a high and very linear gradient field. Rotors with a 3.2 or 4 mm diameter are offered, further on request. Besides imaging applications very slow diffusion processes can be investigated applying the strong gradient fields.

In combination with the Micro2.5 WB gradient system from Bruker, this probe offers new possibilities for sample analysis. The maximum gradient strength of 2.5 T/m along the magic angle is reached if the x, y, z gradients are switched simultaneously.

The MR Microscopy MAS Probe is a customized device which can be configured to special requirements. Please contact the MR Microscopy Product Management before placing an order.
