Zeta Potential Analysis by Meritics Specialists
Zeta potential is also known as the electro-kinetic potential of a colloid. It refers to the charge repulsion / attraction of particles dispersed in a solution, and is measured by applying an electrical field to the dispersive medium. Researchers commonly perform zeta potential measurements to ascertain the longevity and mechanical stability of a particulate solution, and to establish particle agglomeration characteristics for pharmaceuticals, food products, and more. The DelsaMax Pro is a rapid zeta potential analyser capable of measuring sample volumes as small as 45 microliters (μL) in under a second. This speed of measurement is crucial for maintaining sample stability and supporting zeta potential characterisation of fast-moving consumer goods, as overlong exposure to electrical fields can cause analytes to degrade – reducing experiment throughput and results accuracy.
Dynamic Light Scattering
The BeNano Series is the latest generation of nanoparticle size and zeta potential analysers designed by Bettersize Instruments. Dynamic light scattering (DLS), electrophoretic light scattering (ELS), and static light scattering (SLS) are integrated into the system to provide accurate measurements of particle size, zeta potential, and molecular weight. The BeNano Series is widely applied in academic and manufacturing processes of various fields including but not limited to: chemical engineering, pharmaceuticals, food and beverage, inks and pigments, and life science, etc.
