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。

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