主要规格及技术指标

Principle: Dynamic Light Scattering (DLS) is a well-established technique used to measure the particle size and size distribution of molecules or particles (typically in the sub-micron range) dispersed or dissolved in a liquid. The Brownian motion of these particles or molecules causes rapid fluctuations in the intensity of the scattered light they emit. By analyzing these short-term intensity fluctuations, the speed of Brownian motion can be determined, and subsequently, particle size information is derived using the Stokes-Einstein equation.
型号:Zetasizer Lab
原理:动态光散射是一种非常成熟的技术,用于测量分散或溶解在液体中的分子和颗粒(通常在亚微米级)的粒度及粒度分布。这些颗粒或分子的布朗运动导致它们发出的散射光强度出现速波动。通过分析这些短期的强度波动,可以得出布朗运动速度,然后再通过斯托克斯-爱因斯坦方程得出粒度信息。
