Abstract
A nondestructive method for express testing of the state of condensed media is considered. The method is based on the developed new design of a small-sized nuclear magnetic resonance (NMR) spectrometer. The proposed engineering solutions and techniques have made it possible to detect weak-field NMR signals from various nuclei (that have magnetic moments) in a small (less than 0.3 cm3) volume of a condensed medium. This has extended significantly the capabilities of the NMRbased nondestructive method of express testing of condensed media, especially for the purposes of ecological monitoring of hard-to-reach territories. Results of experimental research of various media are presented.
