  • SUBSTANCE PREPARATION METHOD OF CAPSULES AND SYSTEM
    Publication number: 20260210985
    Abstract: The present invention concerns an automated substance preparation method comprising:—providing a first substance container containing a first substance;—a step of sampling to extract at least one portion of the first substance;—determination of a mass of the extracted at least one portion of the first substance;—encapsulating, in a first capsule, the extracted at least one portion of the first substance; and—repeating the step of sampling, mass determination and encapsulating to form a plurality of first capsules of the first substance having randomly distributed different masses of the first substance.

  • Method for NMR spectroscopy or MRI measurements using dissolution dynamic nuclear polarization (DNP) with scavenging of free radicals
    Patent number: 8564288
    Abstract: A method for sample preparation for magnetic resonance measurements using Hyperpolarization by Dissolution Dynamic Nuclear Polarization, involves preparation of frozen beads of a first kind containing paramagnetic substances in addition to the solute under investigation; insertion of the frozen beads into a polarizing magnet; creation of enhanced polarization of nuclei in a magnetic field; heating of the sample to room temperature; transfer of the sample to an MR magnet; and carrying out an MR measurement. In addition, frozen beads of a second kind containing a reducing agent are prepared and inserted into the polarization magnet together with the frozen beads of the first kind. By this method, longitudinal and transverse relaxation times in NMR are extended and free radicals in hyperpolarized solutions are eliminated.
