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.
