High-concentration (40vol%) particle size distribution and zeta potential analyzer AcoustoSizerⅡx

Simultaneous measurements of particle size distribution and zeta potential of high density colloidal particles are realized using unique electro-acoustic method(ESA+multiple frequency analysis) in addition to the ultrasonic attenuation method, which make it possible to evaluate colloidal particles in practical use without dilution.
By applying a unique background automatic correction function of removing the ESA signal due to the electrolyte ions, measurements of highly aculate potentiometric titration and concentration titration of the colloid are realized. And also by establishing an electric double layer distortion theory highly accurate measurement of particle size distribution and zeta potential of various high concentrated colloidal particles are realized.
