Abstract
(EN)
A cell (1) for nuclear magnetic resonance measurement in a liquid medium, comprising: a tank (121) for said liquid medium; a fluid circuit (122) connected to said reservoir and comprising a measurement chamber (124); a gas injector (130) opening into the fluid circuit, at a distance from said measurement chamber; and a coil (141) surrounding said measurement chamber; characterised in that it also comprises at least one capacitive element (142) forming, with said coil, an electromagnetic resonator (140); and in that it has a form allowing its introduction into a nuclear magnetic resonance probe (2) instead of an assembly formed by a tube for nuclear magnetic resonance and a rotor carrying said tube, the coil (141) surrounding the measurement chamber being positioned in such a way as to couple, by induction, with at least one radio-frequency coil (20) of said probe. A nuclear magnetic resonance system comprising such a measurement cell. A method for magnetic resonance measurement using such a cell.
