Solid surface zeta potential is commonly used as a representative for surface charge and gives direct information on processes happening at the solid-liquid interface of a material. Same as electrophoresis is for particles, streaming potential is the method of choice for zeta potential analysis on solids.
Join this webinar to learn about the basic concept of zeta potential analysis on solids, as well as about the benefits of solid surface charge analysis in the fields of...
The surface charge of a membrane gives direct information on electrostatic interactions between a membrane’s surface and compounds in the feed water, which is one cause of membrane fouling. The benefit of the streaming potential method for zeta potential analysis, as presented here, is that membranes can be studied under environmental conditions. It thus allows for visualizing a membrane's behavior in the technical process.
Did you ever think about how shampoo and conditioner adsorb on your hair fibers? Or how they are washed off? Analysis of the change in zeta potential over time will tell you.
In semiconductor industry, surface charge analysis can be applied as a direct tool to monitor wafer cleaning efficiency. It can help to optimize slurry conditions and reduce the efforts in post-CMP cleaning.
Whether you are new to solid surface zeta potential or a critical expert of the technique, you will certainly get a fresh perspective on your solid's surface chemistry.
