  • Patent number: 11009573
    Abstract: A liquid-state nuclear-magnetic-resonance measurement cell includes a reservoir for a liquid medium; a fluidic circuit connected to the reservoir and comprising a measurement chamber; a gas injector opening into the fluidic circuit, at a distance from the measurement chamber; and a coil encircling the measurement chamber; wherein it also comprises at least one capacitive element forming, with the coil, an electromagnetic resonator; and in that it has a shape allowing its introduction into a nuclear-magnetic-resonance probe in replacement of an assembly formed by a nuclear-magnetic-resonance tube and a spinner bearing the tube, the coil encircling the measurement chamber being then positioned so as to couple by induction to at least one radiofrequency coil of the probe. Nuclear-magnetic-resonance measurement system comprising such a measurement cell. Magnetic-resonance measurement method using such a cell is also provided.

  • Patent number: 10365236
    Abstract: There is provided a Nuclear Magnetic Resonance (NMR) measurement cell for use with a solution enabling the introduction of a gas into said solution. The measurement cell includes at least a detection volume designed to be installed in a static magnetic field of an NMR spectrometer, and includes in said detection volume, a gas introduction zone, a measurement chamber for the solution at a distance from the gas introduction zone and a network of conduits for the solution formed to set up fluid communication between the gas introduction zone and the measurement chamber. The gas introduction zone includes at least one gas inlet in the network of conduits, to generate bubbles in the gas introduction zone only. There is also provided a method of manufacturing such a measurement cell and a measurement assembly including such a measurement cell.
