Abstract

A magic-angle spinning adapter and goniometer for an MMR (nuclear magnetic resonance) spectrometer includes a base, a sample slide assembly and a goniometer assembly. This adapter is designed for vertical loading of the solid sample into the NMR probe, and the goniometer permits adjustment of the spinning angle to within 0.1 degree or less. A separate turbine of conventional design permits spinning of liquid samples for typical high resolution solution NMR in the same probe.

Magic Angle Spinning Adapter and Goniometer for NMR Probes Requiring Vertical Sample Loading

A magic-angle spinning adapter and goniometer for an MMR (nuclear magnetic resonance) spectrometer includes a base, a sample slide assembly and a goniometer assembly. This adapter is designed for vertical loading of the solid sample into the NMR probe, and the goniometer permits adjustment of the spinning angle to within 0.1 degree or less. A separate turbine of conventional design permits spinning of liquid samples for typical high resolution solution NMR in the same probe.

The adapter 10 consists of a base 12, a sample slide assembly 14 and a goniometer assembly 16. The base 12 secures the adapter 10 to the NMR probe via an appropriate coupling (not shown). The sample slide assembly 14 slides vertically in order to smoothly insert and extract the sample holder and sample. The vertical slide assembly 14 mates to the base 12 via a dovetail fitting. Smooth travel in the vertical direction is by a rack gearing (not shown) which is controlled by the knob 18. The goniometer assembly 16 includes a rack gearing (not shown) which is controlled by the knob 20. A vernier scale 22 at the top of the goniometer assembly 16 permits adjustment of the spinning axis relative to the magnetic field to one-tenth of one degree or less.
