NMR MEASUREMENT APPARATUS, AND METHOD OF IDENTIFYING SOLVENT

An NMR spectrum is acquired from a nucleus of interest 13C in a solvent included in a sample solution. A spectrum analyzer (50) analyzes a number of splits, a splitting interval, a number of signals, and a signal interval based on the NMR spectrum. Based on these characteristic quantities, an identi...

Zusammenfassung:An NMR spectrum is acquired from a nucleus of interest 13C in a solvent included in a sample solution. A spectrum analyzer (50) analyzes a number of splits, a splitting interval, a number of signals, and a signal interval based on the NMR spectrum. Based on these characteristic quantities, an identifier (54) identifies the solvent. In another configuration, a plurality of NMR spectra acquired from a plurality of nuclei of interest included in the solvent may be analyzed.
