Low-Field and On-Line NMR Detection for Fluid Molecular Structure

doi:10.11938/cjmr20170211

Abstract

Abstract: The molecular structure of fluid influences its physical and chemical properties significantly. Current laboratory analysis methods, such as spectroscopy and spectral method, have the following disadvantages:low measuring efficiency, requirement of chemical reagents, and poor reproducibility. Low-field NMR fluid component analysis is a mature technology. In this study, we developed a set of low-field and on-line NMR fluid detection system and a rapid two-dimensional NMR relaxation measurement pulse sequence, which can be used for rapid, non-destructive, clean, efficient fluid component detection. The performance of the system and the pulse sequence was evaluated experimentally.

Key words: low-field NMR, NMR device, pulse sequence, molecular structure, on-line analysis
