ABSTRACT:
A method and an apparatus serve the purpose of determining the fat or oil content of a sample. The sample is dried under the action of a microwave field and is examined under the action of a radio-frequency signal and of a constant magnetic field by means of nuclear magnetic resonance. The sample is exposed to the microwave field, the radio-frequency signal and the magnetic field at the same measuring place in a common measuring chamber. The apparatus has a microwave source for drying the sample, a magnetic system for generating a nuclear magnetic resonance magnetic field in the sample, and a nuclear magnetic resonance measuring arrangement for irradiating radio-frequency signals into the sample and for receiving excited nuclear magnetic resonance signals from the sample. The microwave source, the magnetic system and the nuclear magnetic resonance measuring arrangement are connected to a common measuring chamber in which the sample is located.
