COMPACT NUCLEAR-MAGNETIC SPECTROMETER FOR EXPRESS-CONTROL OF LIQUID MEDIUM

Design of the handheld nuclear – magnetic spectrometer for the measuring of spontaneous T1 and transverse T2 relaxation times of the liquid medium in low magnetic field B0 = 55 mTl is developed. Julotto method for the measuring of T1 in developed spectrometer design in low magnetic field is implemented for the first time. This method was previously applied only for measurement in strong magnetic field for solid samples in which the ratio of the relaxation times is different from liquid mediums. The nuclear magnetic resonance signal acquisition scheme is developed and realized. This makes it possible to carry out relaxation times measuring for small amount of the liquid medium (10 – 15 gram) when ratio of signal/noise is about 1.5.
