How does the zetasizer work
WebThe Litesizer series employs light-scattering technology to determine not only particle size, but also zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid dispersions. WebFeb 17, 2016 · The Zetasizer is a DLS instrument and generates intensity based (proportional to volume squared) data based on free Brownian motion (which at your sizes is unlikely). Thus they are measuring...

WebThe Z-Average is an Intensity-based calculated value and should never be confused with or directly compared to a Mass or Number mean value produced by other methods. The calculation is defined in the ISO standards, so all systems that use this calculation as recommended should give comparable results if the same scattering angle is used. WebOct 22, 2015 · Bonus for new DLS users: a quick intro to zeta. In addition to the DLS course, Claudia also recorded A Quick introduction to Making a Zeta Potential measurement (6m:50s) which shows an overview of how electrophoretic light scattering and zeta potential work. Note by editor: The above course was designed and recorded by Claudia Mujat.
