Abstract: The present disclosure provides a method for production line nuclear magnetic resonance (NMR) measurement of a fluid containing one or more evaluated materials. The method includes positioning a reference sample with a known reference material and a sample of the fluid within a sensing region of an NMR measurement unit coil and a magnetic field of a permanent magnet. An NMR measurement is performed by feeding at least one radio frequency coil with a signal having a spectrum including characteristic frequencies of the evaluated materials and the reference material, generating detection signals. The detection signals are processed to provide an NMR spectrum with a reference peak and additional peaks. The signal is adjusted based on changes over time of the reference peak frequency, and a band pass frequency range of a receiving unit is adjusted based on the reference peak frequency.
