Abstract
An NMR spectrometer comprises magnetic field producing apparatus for producing a homogenous magnetic field along a magnetic field axis and an elongate sample tube guide extending along a horizontal sample axis through the magnetic field axis in the homogenous magnetic field. A radio frequency coil is positioned around the sample tube guide where the sample tube guide intersects the magnetic field axis. An elongate sample tube is removably inserted into the sample tube guide for positioning a sample in the homogenous magnetic field at a location where the radio frequency coil surrounds the sample tube guide. The magnetic field producing apparatus and the sample tube guide are mounted inside an enclosure. The removable sample tube is connected at one end to a first union mounted in a sidewall of the enclosure and at the other end to a second union mounted in the sidewall of the enclosure. The first and second unions are higher than the horizontal sample tube guide.
