Показано, что данным методом можно измерять параметры различных наночастиц, в том числе и несферических. Представлен экспериментальный образец анализатора динамического рассеяния света для измерений счётной концентрации наночастиц наряду с их размерами.</p></abstract><trans-abstract xml:lang="en"><p>A method is proposed and implemented that allows one to determine the count concentration in the suspension when measuring the particle sizes on the dynamic light scattering analyzer. The applicability of this method to various nanoparticles, including non-spherical ones, has been studied.
