Dynamic light scattering nanoparticle size analyzer NanoBrook

for the pharmaceutical industryfor the cosmetics industryfor molecular biology

The NanoBrook Series size and zeta potential analyzers incorporate all you need for fast, routine, sub-micron measurements of size and zeta potential. Based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, and based on doppler velocimetry (electrophoretic light scattering or ELS) for zeta potential measurement, most measurements only take a minute or two. The instrument also includes Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities. Rapid, Reliable, and Accurate Analysis The NanoBrook Series particle size and zeta potential analyzers are based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, and based on doppler velocimetry (electrophoretic light scattering, ELS) for zeta potential measurement. Most measurements only take a minute or two. These instruments can also be configured with Phase Analysis Light Scattering (PALS) for samples with low mobilities or high conductivity measurements. Three Possible Scattering Angles Measurements of colloids are traditionally made using a 90° scattering angle. For smaller nanoparticles, proteins including IgG, mAbs, and peptides, these < 50 nm samples can be measured using the backscattering angle (173°). Finally the 15° detection angle can be selected for added sensitivity with aggregation measurements. Zeta potential measurements are always performed using the 15° detection angle to minimize diffusion broadening.
