Abstract
A thermostatically controlled containment cell for a sample, suitable notably for a measuring device such as a nuclear magnetic resonance (NMR) spectrometer, NMR type measuring device including the cell, and method for implementation is disclosed. Cell () comprises a body of a tubular sleeve () made of a material so selected as not to interfere with NMR measurements, (for example a non-magnetic and non electrically conducting material) ending at its opposite ends with terminal parts (), containing a sample (S), and means () for circulating within tubular sleeve () a controlled-temperature heat carrier for maintaining the sample at a substantially constant temperature during measurements which liquid is selected to not disturb the NMR measurements. The cell containing the sample is first heated by circulation of the heat carrier. An overpressure sufficient to prevent boiling is established in the cell. The cell can then be introduced into or removed from the NMR measuring device without stopping the circulation of the heating fluid. Applications notably are calibration of logging measurements on geologic samples or others.
