ZetaView® Evolution
Nanoparticle Tracking Analysis
Nanoparticle Tracking Analysis (NTA) is a widely used technique to characterize nanoparticles in liquids. It combines laser light scattering and video microscopy to visualize and track the Brownian motion of individual particles. By analyzing their movement, the particle size (hydrodynamic diameter) and concentration can be determined using the Stokes-Einstein equation.
New Concentration Scanning Technology
Our new innovative Concentration Scanning Technology revolutionizes nanoparticle concentration measurements. The advanced technology captures all particles by scanning the entire measurement volume.
This enables:
- Calibration free measurements
- Direct comparability between different sample types
- Direct comparability between fluorescence and scatter channels
- Precise, reproducible results across a wide concentration range: 10⁵ – 10⁹ particles/ml
Zeta potential
Zeta potential is the electrical potential at the slipping plane of a particle suspended in a fluid. It indicates the degree of electrostatic repulsion or attraction between particles and is a key parameter for predicting the stability of colloidal dispersions. A high absolute zeta potential (either positive or negative) suggests strong repulsive forces, which helps prevent particle aggregation.
The ZetaView® Evolution can measure Zeta potential directly inside its quartz glass measurement cell – no need for disposables.
