  • Holding of NMR measurement samples in a space-restricted NMR spectrometer
    Patent number: 12399239
    Abstract: An NMR spectrometer (10) with a permanent magnet device (11) with measurement volume (12) and bore (13) for inserting an NMR measurement sample contained in a sample tube (14), and with an RF coil (15) outside a cylindrical temperature control pipe (16) with a continuous annular air gap (17) through which temperature control gas can be conducted through a gas inlet (18), is characterized in that on the end opposite the gas inlet, a movable holding device (19) is installed which, in a first operating position, does not touch the sample tube, in a second operating position, holds the sample tube in its measuring position at its outer circumference in a force-fitting and/or form-fitting manner with an axially acting force or static friction Ff, and, in a third operating position, releases the sample tube for removal, and that in the second operating position Ff>Fdynamic?Fweight, where Fdynamic is the buoyancy force generated by the dynamic pressure of the temperature control gas flowing onto the sample tube a
