We consider the special features involved in studying flows of liquid media using a nuclear magnetic resonance spectrometer. Taking these special features into account in the design of the NMR spectrometer lets us determine the relative concentrations of paramagnetic ions, and also lets us measure the longitudinal (T1 ) and transverse (T2 ) relaxation times within <0.5% in liquid flows. This lets us completely eliminate errors in determining the state of the flowing medium using the measured relaxation constants T1 and T2, which is especially important when working with medicinal suspensions and biological solutions. We present the results of experimental studies on flows of liquid media.
