Abstract
A streaming potential device for work with dispersed material is described. The use of a vibrating condenser electrometer-amplifier in connection with a paper strip recorder gives the possibility to perform measurements in short time and with small volume of liquid. Statistical analysis of the results on quartz particles of three different sizes in KCl solutions (1 X 10-s to 5 X l0-3 N) is given. The determination of the ~-potential with this device and experimental technique can be performed with a standard error of about 5%.
