Zeta 电位、大分子的分子量等都可以通过现在的 DLS 测量，其中 Zeta 电位的测量是

DLS 运用波的多普勒效应测得带电粒子的淌度，根据电化学原理将其转化。Zeta

电位实则表示的是连续相与流体稳定层之间的电势差，表征分散液体系稳定性的

指标就是 Zeta 电位，其绝对值越高，分散液体系越稳定。

The Zeta potential, molecular weight of macromolecules, etc., can all be measured by the current DLS, where the Zeta potential is measured DLS uses the Doppler effect of waves to measure the mobility of charged particles and converts them according to electrochemical principles. Zeta.The potential actually represents the potential difference between the continuous phase and the fluid stable layer, which characterizes the stability of the dispersed liquid system .The index is the Zeta potential, the higher the absolute value, the more stable the dispersed liquid system.
