Applications of low field NMR: Relaxation measurements and resin curing
Nuclear magnetic resonance (NMR) is a powerful analytical tool that allows for noninvasive and nondestructive characterization of the chemical composition of a sample. Furthermore, low field NMR (B0 < 1 T) offers many potential advantages when compared to high field NMR, such as lower costs, smaller size, portability, lower power consumption and the ability to detect through thin metal layers. The versatile characteristics of low field NMR have allowed it to be used for a variety of practical applications. In this talk, I will discuss work being done to measure the T1 and T2 relaxation times on the components of the ISMRM/NIST system phantom at field strengths between 6.5 - 550 mT. To emphasize the versatility of low field NMR as an analytical tool, I will then discuss the use of single-sided NMR to monitor the curing process of 3D printing compatible resins.
