Bidirectional oscillating streaming potential method

Bidirectional oscillating streaming potential method
DataPhysics Instruments patented a measuring technique that uses an oscillatory flow of electrolyte solution through or along the sample. The streaming potential and the currently applied pressure are measured simultaneously together with the temperature, conductivity and pH value of the electrolyte solution. Through the wide range of applicable flow frequencies and amplitudes a fast and precise measurement is possible.
The DataPhysics ZPA 20 zeta potential analyzer is a compact measuring instrument that utilises the patented bidirectional oscillating streaming potential method. It is designed to measure the zeta potential of various macroscopic solid samples with highest accuracy and within shortest time.
