Particle Shape Characterization
Advanced Particle Shape Characterization with Light Scattering Techniques
Understanding particle shape is critical in a wide range of industries, from pharmaceuticals to materials science. Particle shape impacts flow behavior, stability, performance, and functionality in complex systems. With advanced light scattering techniques, you can achieve precise, non-invasive, and efficient characterization of particle shape, enabling you to optimize your processes and products.
Why Characterize Particle Shape?
Particle shape plays a key role in defining material properties, such as:
- Rheological behavior: Shape influences viscosity and flow characteristics in suspensions.
- Optical properties: Irregular shapes scatter light differently, impacting clarity and appearance.
- Stability and aggregation: Shape can dictate the behavior of particles in colloidal systems.
- Performance optimization: From drug delivery to coatings, shape impacts functionality and efficacy.
How to Characterize Particle Shape?
Our solutions leverage static light scattering (SLS), dynamic light scattering (DLS), and depolarized light scattering to provide comprehensive insights into particle shape, size, and behavior.
Static Light Scattering (SLS)
- What it does: Measures angular intensity patterns of scattered light to provide information about the overall size and structure of particles.
- Key Benefits: Ideal for determining shape factors and polydispersity in larger particles.
- Applications: Powder analysis, polymer science, and particle suspensions.
Dynamic Light Scattering (DLS)
- What it does: Analyzes fluctuations in scattered light intensity to measure the hydrodynamic size of particles in suspension.
- Key Benefits: Quick and reliable characterization of size distributions with sensitivity to particle anisotropy.
- Applications: Nanoparticles, proteins, and other small colloidal systems.
Depolarized Static and Dynamic Light Scattering (D-SLS/D-DLS)
- What it does: Exploits depolarization effects to identify and quantify asymmetry in particle shape.
- Key Benefits: Non-invasive and highly sensitive to shape anisotropy in both dilute and concentrated systems.
- Applications: Rod-shaped particles, platelets, other non-spherical geometries, and optical anisotropies.
