Abstract
The invention relates to a NMR method for determining moisture content of a sample, in which method a sample is subjected to a magnetic DC-field, the sample under magnetic DC-field is subjected to a sequence of excitation pulses in RF-frequency with pulse interval for exciting hydrogen nuclei, and NMR signal of the excited hydrogen nuclei is measured. In accordance with the invention spin-lattice relaxation time is estimated for the sample, and pulse interval is adjusted longer than the estimated spin-lattice relaxation time.
