We review a powerful regularization method, known as CONTIN, for obtaining the size distribution of colloidal suspensions from dynamic light scattering data. We show that together with the so-called L-curve criterion for selecting the optimal regularization parameter, the method correctly describes the average size and size distribution of microgel suspensions independently characterized using small-angle neutron scattering. In contrast, we find that when using the default regularization process, where the regularizer is selected via the “probability to reject” method, the results are not as satisfactory.

CONTIN算法及其在确定微凝胶悬浮液粒径分布中的应用

我们回顾了一种强大的正则化方法,称为CON​​TIN,用于从动态光散射数据获得胶体悬浮液的尺寸分布。我们表明,与用于选择最佳正则化参数的所谓L曲线准则一起,该方法正确地描述了使用小角度中子散射独立表征的微凝胶悬浮液的平均尺寸和尺寸分布。相反,我们发现,当使用默认的正则化过程时,通过“拒绝概率”方法选择了正则化器,结果并不令人满意。
