Scope
Scope: This document specifies the method for determining the 17O-NMR half-peak width of water quality using nuclear magnetic resonance (NMR) technology. This document is applicable to the determination of the 17O-NMR half-peak width of water quality; Main technical content: At present, there is no standard for determining the 17O-NMR half-peak width of water quality in China. The purpose of this document is to unify and standardize the current NMR half-peak width determination technology in the market, and to replace the concept of "small molecular clusters" with the technical indicator of "17O-NMR half-peak width (17O-NMR FWHM)".
