Multi angle laser light scattering instrumentThe core principle is based on the scattering effect of light. When a laser beam is irradiated onto molecules or particles in a solution, the light interacts with the electron cloud in the molecules, resulting in scattering phenomena.

Multi angle laser light scattering instrumentTechnical features:

Direct measurement of absolute molecular weight:

By using static light scattering technology, the absolute molecular weight information of polymer materials can be directly obtained, avoiding the limitations of traditional methods that rely on standard sample calibration.

High precision and wide measurement range:

Molecular weight range:10³to10⁹Dalton, covering low molecular weight to ultra-high molecular weight.

Molecular size range:10Nano to500Nano, suitable for the characterization of nanoparticles and macromolecules.

Multi angle synchronous detection:

Collecting scattering data from multiple angles simultaneously provides more comprehensive information, especially suitable for analyzing the branching and dispersion of complex systems.

No sample pretreatment required:

It can directly measure liquid samples, reduce operational steps, and minimize human errors.

Automation and high sensitivity:

Automated operations reduce manual intervention and improve experimental efficiency.

High sensitivity detection can still be maintained for low concentration samples.
