ABSTRACT:
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.
