Measuring Zeta Potential in High Salt Concentration Samples | Mastering the Zetasizer!
Many customers use the Zetasizer series for measuring the size, zeta potential, and molecular weight of nanoparticles, colloids, and proteins. Here, we introduce a method to measure the zeta potential in high salt concentration samples using the Zetasizer Nano.
Have you ever struggled with measuring zeta potential?
The biggest attraction of the Zetasizer is its ease of measurement.Even with default settings, the device optimizes the conditions.
Zeta potential measurement uses electrophoresis.With buffer electrophoresis, heat may be generated near the electrodes,
and electrolysis can occur.Therefore, setting measurement conditions requires some tips.This time, we will guide you on setting measurement conditions using buffers for zeta potential.
