Abstract
A solid-state nuclear magnetic resonance probe that includes multiple sample spinning systems and detection coils is disclosed. The probe can be repositioned within the bore of the magnet to selectively maximize the throughput and sensitivity of the instrument by acquiring a spectrum from one sample at a time while at least one other sample is at or returning to an equilibrium spin state. Methods for the utilization of the probe are also disclosed.

A solid-state nuclear magnetic resonance probe for use in a magnetic field, the probe comprising:
- a housing, the housing being moveable to different positions within the magnetic field;
- a plurality of isolated spinning modules positioned within the housing, the isolated spinning modules being configured to hold different samples for sequential solid-state NMR analysis;
- and
- wherein the housing is configured for the movement of one of the plurality of modules out of a homogeneous portion of the magnet to allow a sample contained with the one of the plurality of modules to return to an equilibrium state.
A system for use in solid-state nuclear magnetic resonance spectroscopy, the system comprising:
- a probe, the probe comprising,
- (1) a housing, and
- (2) a plurality of isolated spinning modules positioned within the housing, the isolated spinning modules being configured to hold different samples for analysis;
- a repositioning device coupled to the probe, the repositioning device being configured to alter the position of the probe to place a spinning module within the homogeneous portion of a magnet;
- and
- an acquisition device coupled to the spinning modules, the acquisition device being configured to acquire a spectrum from only the spinning module that is placed within the homogeneous portion of a magnet.
A solid-state nuclear magnetic resonance spectrometer, comprising:
- a magnet, the magnet defining a bore;
- a probe, the probe comprising,
- (1) a housing sized to fit within the bore of the magnet, and
- (2) a plurality of isolated spinning modules positioned within the housing, the isolated spinning modules being configured to hold different samples for analysis;
- a repositioning device coupled to the probe, the repositioning device being configured to alter the position of the probe to place a spinning module within the homogeneous portion of a magnet and remove a second spinning from the homogeneous portion of the magnet;
- and
- an acquisition device coupled to the spinning modules, the acquisition device being configured to acquire the signal from only one of the isolated spinning modules during an acquisition of a spectrum.
A method for the analysis of sample, the method comprising the steps of:
- providing a magnet, the magnet defining a bore;
- providing a probe, the probe being positioned within the bore of the magnet;
- providing a plurality of spinning modules within the probe;
- placing a plurality of samples within the plurality of spinning modules;
- positioning the probe within the bore of the magnet to position a first spinning module in a first position;
- acquiring a first spectrum from a first sample contained within the first spinning module;
- moving the probe from the first position to a second position that positions a second spinning module for the acquisition of a second spectrum from a second sample contained within the second spinning module.
