Detailed description:

Dynamic Light Scattering (DLS) Wyatt DynaPro NanoStar with Wyatt Dynamics software package

Description

Based on the Brownian random motion used for calculation of particles size/distribution (hydrodynamic radius, Rh) of measured structures dissolved/dispersed in solution.

Applications

- Used for analysis of proteins, micelles, colloids, metallic nanoparticles, quantum dots
- Study of particles interactions, particles stability in solutions, surface modification of particles

Specifications

- Rh from 1 ̶ 2500 nm
- Very small volume of samples from 1 μL (from 4 μL with disposable cuvettes)
- „Standard“ high-volume quartz cuvette with silicon lid eliminating solvent evaporation
- Analysis in aqueous solution and in organic solvents
- Temperature range from 10 ̶ 100°C, laser wavelength 658 nm
- Analysis of very diluted samples (0.1 mg/mL pro lysozyme)
