Abstract. The article presents the results of the development of the reference materials of the zeta potential of particles in a liquid MDP-M45, MDP-M60, MDP-M90, MDP-P45, MDP-P70, MDP-P90, based on a sol of silver nanoparticles stabilized with an amino acid. Studies have been conducted aimed at obtaining a stable dispersed system with reprodu­cible zeta potential values. As a result, the reference materials of the zeta potential of particles in a liquid with average values were obtained: minus 45; minus 60; minus 90; plus 45; plus 70; plus 90 mV, while the relative error of reproducing the zeta potential (the average value of the zeta potential) does not exceed ± 8 %. The results of the study can be used for metrological support of measurements of the zeta potential of dispersed systems.
