- A model LL-4 magnetic resonance low level unit designed to operate at 5.35 MHz was used to perform proton magnetic resonance ([sup 1]H-MR) tests on sugar solutions. The magnet console was designed and built by Agricultural Engineering Department personnel. The homogeneity of the magnetic field is critical to achievement of a good signal and to good performance of the device. Measurements of magnetic field strength along the major axes of the air gap are reported. Test tubes were filled with sugar solutions and placed in the air gap between the permanent magnets in the magnet console. Sugar solutions containing 0% to 30% sucrose were interrogated using, the Hahn spin echo pulse sequence. The amplitude of the echo peak was well correlated with percent sugar content in solutions.
