Abstract

This paper reports our work in developing a mobile nuclear magnetic resonance system with full spectroscopy capability. The system consists of a 0.93 T, portable permanent magnet, a 8-turn 550 µm diameter microcoil, and compact electronics systems. The system provides 0.4 parts per million spectrum linewidth and 408 signal-to-noise ratio from a 37 nL water sample with 128 averages. Representative (1)H and (19)F spectra are presented.

摘要

本文报道了我们开发具有全光谱能力的移动核磁共振系统的工作。该系统由一个0.93 T的便携式永磁体、一个8匝、直径550 µm的微线圈和紧凑的电子系统组成。该系统从37 nL的水样中，经128次平均测量，可提供百万分之0.4的谱线宽度和408的信噪比。文中给出了代表性的氢谱和氟谱。
