We present the rapid and quantitative characterization of ionic, non-ionic and zwitterionic surfactants based upon the combination of an automatic continuous mixing technique and static light scattering. Collection and subsequent analysis of data are both rapid and semiautomatic, which increases precision, sensitivity, and range of applicability while substantially decreasing the amount of manual intervention required by the investigator. By treating the continuous data, the entire data set may be rapidly analyzed in the context of the closed association model to determine the critical micelle concentration cmc and aggregation number Nag of a detergent; these technique are comparable in the scope and resolution currently obtainable from other conductimetric, fluorescence and surface tension techniques.
我们基于自动连续混合技术和静态光散射的结合，对离子型、非离子型和两性离子型表面活性剂进行了快速定量表征。数据的收集和后续分析既快速又半自动，这提高了精度、灵敏度和适用范围，同时大幅减少了研究者所需的人工干预量。通过处理连续数据，可以在封闭缔合模型的背景下快速分析整个数据集，以确定洗涤剂的临界胶束浓度cmc和聚集数Nag；这些技术在目前可从其他电导、荧光和表面张力技术获得的范围和分辨率方面具有可比性。
