Particle Sizing & Zeta Potential

Brookhaven are dedicated to particle size determination. They offer a full range of instruments for dynamic light scattering (high and low resolution; particles from 0.3nm to 10 microns), Zeta Potential, molecular weight determination, dielectric constant determination, microrheology, surface zeta potential and static light scattering at the research level.

BI-DCP & BI-XDC: High Resolution Particle Sizing with both light and X-ray sources

Based on first principle of photo-sedimentation, the Brookhaven Instrument disc centrifuge instruments are the only optical disc centrifuge that measures particle size without calibration. The DCP has a traditional light source and the XDC use X-rays. These instruments measure the size of particles according to the time the particle takes to sediment in the detector according to Stokes Law. High resolution measurements are typically obtained in 5 to 30 minutes. Modelling software is included to predict optimal experimental conditions like disc speed and run time. The high resolution instrument can resolve peaks as close as a 13% size differential and…

BI-200SM Research Goniometer and Laser Light Scattering System

The BI-200SM goniometer is a world class Static Light Scattering (SLS) instrument at the research level. Key features: • nanoparticle characterization • particle size distributions • protein and polymer characterization • molecular weight • complex fluid characterization The Brookhaven Instruments’ BI-200SM system opens the door to the rich fields of exploration of both Static Light Scattering (SLS) and Dynamic Light Scattering (DLS). The BI-200SM Research Goniometer System provides access to these studies with an automatic, modular and versatile system. It is a precision instrument designed for exacting scattering measurements. Based on a special turntable with precision ball bearings and stepping…

DLS particle size & Zeta Potential – The NanoBrook Family

Brookhaven offer a range of instruments for determination of particle size by DLS and Zeta Potential. The NanoBrook series offer a full range of instruments for particle sizing from 0.3nm to 10 micron with DLS. Zeta Potential is also available in the same instruments. Molecular weight determination, dielectric constant determination, microrheology, and surface eta potential can all be controlled by one single data acquisition software, the eminently powerful ‘particle solutions’. DLS sizing features: • rapid and accurate protein and nanoparticle size distributions • multimodal and unimodal size distribution software • ISO 13321 and ISO 22412 compliant results • range: >…
