WebJun 11, 2015 · In the Zetasizer a range of different attenuators can be used, and in automatic mode the system will select an attenuation level to achieve a mean count rate in the optimal 200-500kcps range. In the Zetasizer microV and the APS there is even more fine-tuning available because the laser intensity may also be independently adjusted.
WebThe Zeta Potential Analyzer can measure solid, fibers, or powdered material. The motor found in the instrument creates an oscillating flow of electrolyte solution through the sample. Several sensors in the instrument monitor other factors, so the software attached is able to do calculations to find the zeta potential. 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.
WebJul 10, 2024 · The process typically works as follows: The laser is focused on the sample through the lense. Light is scattered by the particles. A detector, typically placed at 90 degrees (or 173 degrees, depending on the particular Zetasizer Advance model) to the light source, collects the scattered light.
