At present, the water quality 17O-NMR half-peak width measurement standard has not yet been formulated in China. This document is proposed to unify and standardize the measurement technology of 17O-NMR half-peak width on the current market, with "17O-NMR half-peak width (17O-NMR FWHM) "Technical indicators replace the concept of "small molecular groups".
