Liquid Zeta Potential/Potentiometry (DLS) Analysis Service
Liquid zeta potential and dynamic light scattering (DLS) analysis are powerful techniques for comprehensive physical characterization of dispersed particles and colloids. These methods provide crucial insights into the surface charge, stability, and size distribution of materials - vital information for the development, optimization, and quality control of a wide range of environmentally-friendly formulations.
At the core of DLS analysis is the measurement of particle size distribution based on the dynamic fluctuations of light scattered by particles undergoing Brownian motion. The intensity of scattered light varies with time due to the random motion of particles, and these fluctuations are analyzed to determine the size distribution.
Zeta potential analysis, on the other hand, focuses on the electrical charge of particles at the shear plane. It is measured by observing the velocity of particles in an applied electric field. The zeta potential is a key indicator of colloidal stability; particles with high zeta potential values tend to repel each other, preventing aggregation and thus maintaining stability.
Small Sample Volumes
These techniques require only small amounts of sample, typically in the range of milliliters, making them well-suited for cases where sample availability is limited.
Versatile Compatibility
Both zeta potential and DLS analysis can be performed in a variety of aqueous and non-aqueous solvents, as well as at different temperatures and pH levels, providing flexibility for diverse sample types.
Rapid Analysis
These techniques offer fast, automated data collection and analysis, allowing for efficient high-throughput screening and routine quality control applications.
At CD BioSciences, we pride ourselves on offering comprehensive DLS analysis services that are tailored to meet the specific needs of our clients in the environmental sector.
At the heart of our zeta potential and DLS analysis services are two complementary techniques:
Electrophoretic Light Scattering (ELS)
This method measures the velocity of charged particles moving in an applied electric field, which is then used to calculate their zeta potential. ELS provides direct insights into the surface charge characteristics of the sample, crucial for understanding particle stability and interactions.
Dynamic Light Scattering (DLS)
Also known as photon correlation spectroscopy, this technique analyzes the Brownian motion of particles to determine their hydrodynamic size distribution. DLS data allows for the precise quantification of particle size, size uniformity, and potential aggregation or agglomeration.
To ensure the highest quality of analysis, we have specific requirements for sample preparation and types:
