We have developed a new magic angle spinning (MAS) system which enables very fast MAS up to 80kHz. The sample tube has an outer diameter of 1mm and has an active volume of 0.8μL. The rotor can spin very stably from a very low spinning speed of 1kHz to the maximum speed of 80kHz. Spinning fluctuation is within ±5~10Hz at any spinning speed.
