A Compact Nuclear Magnetic Relaxometer for the Express Monitoring of the State of Liquid and Viscous Media

A compact nuclear magnetic relaxometer is developed, which enables the longitudinal and transverse relaxation times of liquid and viscous media to be measured in a weak magnetic field. The Julotto method is used for the first time to measure the longitudinal relaxation time in the relaxometer. A cir...

Description
Summary:A compact nuclear magnetic relaxometer is developed, which enables the longitudinal and transverse relaxation times of liquid and viscous media to be measured in a weak magnetic field. The Julotto method is used for the first time to measure the longitudinal relaxation time in the relaxometer. A circuit for storing the nuclear magnetic resonance signal is developed and constructed, which has enabled the relaxation time to be measured for a small number of media with the minimum signal-to-noise ratio.
