Determining the rheological behavior of sucrose solution using the BeNano 180 Zeta
4 Oct 2023In this application note, the BeNano 180 Zeta nanoparticle size and zeta potential analyzer from Bettersize Instruments was employed to analyze sucrose samples at various concentrations. The study aimed to characterize the viscoelastic properties of the solutions using dynamic light scattering microrheology (DLS microrheology). This technique utilizes dynamic light scattering to measure the mean square displacements of inert tracer particles added to a solution, providing valuable rheological information about weakly structured polymer and protein solutions, as well as gel systems, where tracer particles diffuse over significant distances.

RheometryRheometers are used to measure the rheology of fluids, which is the flow of fluids in response to an applied force. The most common types of rheometer include shear rheometers (capillary, cone and plate and rotational cylinder) and extensional rheometers. Viscometers are similar to rheometers however viscometers only measure the viscosity of a fluid.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
