For the analysis of size, concentration, fluorescence, electrophoretic mobility and sub-populations of individual nanoparticles.
For size, concentration, zeta potential and cluster analysis of individual particles in two different fluorescence channels.
For size, concentration, zeta potential and cluster analysis of individual particles in four different fluorescence channels.
We measure your products in a measuring range of 0.8 nm to 300 μm, if possible in original concentration
For the analysis of size, concentration, fluorescence, electrophoretic mobility and sub-populations of individual nanoparticles
Nanoparticle Tracking Analysis (NTA) captures the Brownian motion of each particle in the video. Based on the different diffusion movements of large and small particles in the surrounding liquid, the hydrodynamic diameter of the particles is determined. Furthermore, the charge state of the particle surface (zeta potential) can be measured via the movement of the particles in an applied electric field.
Pattern parameters, such as intensity fluctuations, surface geometry and shape of the particles as well as particle concentration are documented at each recording and can be used to distinguish sub-populations.
All these analyzes are carried out quickly and statistically reliably as required in the scattered light or fluorescence mode.
