The characterization of proteins, polymers and nanoparticles often presents users with a complex choice of instruments. The highly configurable NanoBrook range of products from Brookhaven Instruments now makes that choice easier.
The NanoBrook Series is a Configurable Platform for Particle Sizing and Zeta Potential Measurements
The NanoBrook Series size and zeta potential analyzers integrate all the features required for rapid, routine, sub-micron measurements of both size and zeta potential.
A majority of the measurements are based on the principles of Doppler velocimetry [electrophoretic light scattering (ELS)] for zeta potential and based on dynamic light scattering (DLS) for particle sizing and distribution. Such measurements take only a minute or two.
Besides this, the instrument allows phase analysis light scattering (PALS) measurements for samples that have low mobility.
The NanoBrook Omni Combines all of the Most Common Configurations
The NanoBrook Omni allows users to quantify samples in virtually every possible suspension environment, ranging from high salts like seawater and PBS to aqueous solutions and organic solvents. Particle and protein sizing, with maximum sensitivity, use three measurement angles for truly neutral measurement results.
