High Concentration Zeta Potential Measurement Device using Electric Acoustic Method - ZetaProbe
Automatically measure the zeta potential of high-concentration colloidal particles in their original solution. The isoelectric point is also measured automatically.
In ZetaProbe, an alternating voltage is applied to the solution, and the zeta potential is measured from the ESA signal generated by the vibrations of colloidal particles. In high-concentration colloidal solutions, light cannot penetrate, making measurements using optical methods difficult; however, the electroacoustic method uses sound waves, allowing for the measurement of zeta potential even in more concentrated solutions. There is no need to worry about changes in electrolyte concentration or pH due to dilution. 【Features】 - Compatible with high-concentration and high-viscosity samples, allowing measurements in the original solution. - High-precision measurements possible using electroacoustic methods and multi-frequency analysis [patent obtained]. - Accurate zeta potential measurements can be made. → Signals from ions similar to those from particles are removed through background correction. - Parameters can be changed later for re-analysis. - An automatic titration system necessary for isoelectric point measurements is standard equipment.
