Abstract: NMR today is commonly understood to be a powerful but expensive analytical method that relies on strong and bulky superconducting magnets. But it started with permanent and electromagnets at lower field strengths for materials characterization by relaxation measurements and shortly after, as the field homogeneity improved, with chemical shift spectroscopy for molecular analysis. While NMR relaxometers could be shrunk to fit the tabletop over 40 years ago it took 30 more years to arrive at tabletop spectrometers following the development of mobile relaxometers for nondestructive materials testing. After a short historical review, recent applications of mobile NMR to biofilms in Yellowstone National Park and master violins in Cremona are reported, as well reaction monitoring with the reactor and a compact NMR spectrometer in the fume hood of the chemistry laboratory.
