description: This work is devoted to the assessment of the aggregation stability of colloidal solutions on the developed laboratory prototype of the zeta potential analyzer, which is based on the method of electrophoretic light scattering. After a brief analysis of the shortcomings of methods for obtaining the zeta potential of colloidal particles, it is explained why the electrophoretic light scattering method was chosen for this work. Since commercial devices designed for this task also have their drawbacks, the task of developing and improving a laboratory analogue is relevant. For the developed measuring complex, options for improving the signal-to-noise ratio, optimizing the operation of the device, and minimizing errors are proposed. On the developed device, test studies were carried out on differentsized latex microspheres to test the operation of the device in the case of different values of the Henry function. The results of the test measurements are compared with the values obtained for the commercial Zetasizer Nano device. This is necessary to evaluate the measurement accuracy of the created analyzer. For the studied colloidal systems, the electrophoretic mobility and zeta potential are calculated according to the formulas given in the theoretical part, based on the obtained values of the latter, a conclusion is made about the stability of the studied systems.
