Pulsed field gradient NMR (PFG-NMR) is an important method for the characterisation of emulsions. Apart from its application in quality control and process development, especially high-field NMR methods can be applied to investigate emulsions properties on the molecular level. Meanwhile, complex emulsion structures such as double emulsions have been developed and require analytical tools especially for the determination of droplet size distributions. This contribution provides an overview on the possibilities and methods of PFG-NMR referring to measurement, data processing and interpretation of droplet size distributions. Comparison of techniques and measurements on double emulsions are presented.
脉冲梯度核磁共振（PFG-NMR）是一种用于乳状液特性描述的重要方法。除了在质量控制和工艺开发中的应用外，特别是高场 NMR 方法还可以用于研究乳状液的分子水平特性。同时，复杂的乳状液结构（如双乳液）已经被开发出来，需要分析工具，特别是用于测定液滴尺寸分布。本贡献提供了关于 PFG-NMR 的可能性和方法的概述，涉及液滴尺寸分布的测量、数据处理和解释。还介绍了对双乳液的技术和测量的比较。
