摘要： A nuclear magnetic resonance spinning apparatus includes an elongated cylindrical sample rotor with slotted air vanes on one tapered end thereof, an axial stator air drive and air end bearing, and a lateral ring air bearing around the opposite end of the rotor. The lateral end bearing retains the spinning axis at a precise pre-set angle, and the slotted air vanes are designed for high speed, low pressure applications. An adjustable cradle support mounts the spinning apparatus in a manner that allows convenient spin angle adjustment, and an insulated probe is provided with a convenient access opening and door structure for access to the spinning apparatus mounted therein.

摘要： A technique and design for variable-temperature magnetic resonance spectroscopy. Designs utilizing a separate gas for control of sample temperature confine temperature gradients away from the sample. Annular seals isolate a sample gas chamber along a rotor and avoid gas mixing and other sample temperature effects. Improved resolution by avoiding temperature gradients and independence of rotational speed from sample temperature is provided.

摘要： An automatic liquid sample changer for use with a magnetic resonance spectrometer and having separate upper and lower openings in a sample container guide tube to allow a sample container to pass into an analysis area from a superior positioned storage rack, and then subsequently from analysis area into an inferior positioned storage rack, and wherein gravity acts as the means for transporting a sample container through the system. Air bearing or other supports which do not frictionally engage sample container are used to delocalize spin wobble of sample container within sample container guide tube. The first, also acting as a spin drive is proximal to open end of sample container. The second is proximal to the closed end of sample container. A unitary means for sealing, rotor and vortex plug device enhances spectra, aids in reducing wobble and maintains a proper seal of sample container. Economical as well as reliability characteristics are realized as mechanical parts have been minimized and both ejection air and mechanical arms are eliminated.
