Abstract
A standard method has been developed for the production of reference materials for NMR relaxation time measurement. These are based on agarose gels doped with gadolinium. The reproducibility and temporal stability of the gels have been found to be excellent. Electron microscope studies have shown good homogeneity. The relaxation behavior of such gels has been mathematically modeled with good agreement with experiment.
摘要
已开发出一种用于生产核磁共振弛豫时间测量参考材料的标准方法。这些材料基于掺杂钆的琼脂糖凝胶。已发现凝胶的重现性和时间稳定性极佳。电子显微镜研究显示其具有良好的均匀性。此类凝胶的弛豫行为已通过数学建模，结果与实验吻合良好。
