Аннотация: It is demonstrated that the use of pressure extends the possibilities of capillary zone electrophoresis in studying aggregative states of substances, ensuring the detection of the presence of several types of aggregates with different electrophoretic mobilities. The electropherograms of chitosan 2-hydroxybutoxypropylcarbamate (CHBPC) in citrate solutions with pH 3.1, 4.5, and 5.8 indicate the dependence of aggregation on pH. A comparison of the data for CHBPC obtained by capillary zone electrophoresis, static light scattering, and scanning electron microscopy revealed a relationship between the electrophoretic mobility and sizes of aggregates, varying from 140 nm to several micrometers. The size of aggregates can be estimated by hydrodynamic contribution to their mobility. The effectiveness of the use of CHBPC for the dynamic modification of capillaries is shown.
