Light scattering instruments, such as Dynamic Light Scattering (DLS), Electrophoretic Light Scattering (ELS), and Multi-Angle Light Scattering (MALS), are essential tools for analyzing particles and molecules in solutions. These techniques help researchers measure properties like particle size, molecular weight, surface charge, and structure. They are widely used in industries such as pharmaceuticals, biotechnology, nanotechnology, and polymer science for both research and quality control.
Dynamic Light Scattering (DLS) measures the size of particles by observing their motion in solution. It is commonly used to study protein aggregation, ensuring stability in biopharmaceuticals, and to analyze nanoparticles like micelles and liposomes, which are crucial for drug delivery systems. Instruments like the DynaPro series are ideal for high-throughput analysis and low-concentration samples, supporting efficient workflows.
Electrophoretic Light Scattering (ELS) focuses on zeta potential, which measures particle surface charge and indicates stability. This is essential for optimizing formulations, such as suspensions and emulsions, by guiding the use of stabilizers or adjusting pH levels.
Multi-Angle Light Scattering (MALS) provides detailed measurements of molecular weight, size, and shape without needing calibration standards. Combined with chromatography (e.g., SEC-MALS), MALS is used in biopharmaceuticals to analyze proteins, antibody-drug conjugates, and viral vectors. It is also valuable in polymer science for studying molecular weight distributions and branching. Instruments like the DAWN and miniDAWN offer precise, high-resolution data for these applications.
Wyatt"s systems integrate with complementary technologies, such as Field-Flow Fractionation (FFF), to separate particles by size before analysis, and concentration detectors like Optilab RI, which enhance measurement accuracy. These tools allow for detailed characterization of complex samples, including protein aggregates and nanoparticles.
Light scattering techniques are applied across industries for tasks such as improving protein stability in pharmaceuticals, characterizing nanoparticles in nanotechnology, and studying polymers for material science. Their ability to provide non-destructive, high-precision measurements makes them versatile and indispensable in modern research and development. Wyatt"s instruments are known for their reliability, accuracy, and ease of integration, helping scientists gain deeper insights and drive innovation in their fields.
