DISC CENTRIFUGES FOR PARTICLE ANALYSIS The Brookhaven BI-DCP is a digitally controlled, high resolution, particle size distribution analyzer. It yields high resolution results in the size range from 0.01 to 30 microns with typical analysis timesranging from 5
BI-870 DIELECTRIC CONSTANT METER The BI-870 can accurately measure in low and high dielectric solvents, including mixed liquids and solutions. The BI-870 has two selectable sensitivity ranges: 1-20 and 1-200. Absolute accuracy is ± 2%, while repeatability and linearity accuracy is better than 0.2%.

ABOUT US - BROOKHAVEN INSTRUMENTS Brookhaven Instruments was founded in 1981 by Dr. Bruce Weiner, a physical chemist, and Dr. Walther Tscharnuter, a physicist. The two met in 1970 as postdoctoral associates working under Prof. Ben Chu at Stony Brook University, who was leading one of the only laboratories in the world at that time investigating Dynamic Light Scattering(DLS).
PARTICLE CHARACTERIZATION APPLICATIONS Zeta Potential. Almost all particulate or macroscopic materials in contact with a liquid acquire an electronic charge on their surfaces. Zeta potential is an important and useful indicator of this charge which can be used to predict and control the stability of colloidal suspensions or emulsions. PARTICLE SOLUTIONS SOFTWARE Particle Solutions is a powerful new suite of software. It integrates five different measuring technologies: DLS, ELS, PALS, μRhe, and ASEC in one package. Measurements made with earlier versions of Brookhaven Instruments software can be imported into Particle Solutions, and then analyzed with the same powerful tools. Request a Software License.

The BI-SCP is compatible with the SREL solvent-resistant WHAT IS DYNAMIC LIGHT SCATTERING? This method is used to obtain parameters such as M w, R g, and A 2. In contrast, Dynamic Light Scattering (DLS) exploits the collective motion of a large ensemble of randomly oriented particles dispersed in some medium. DLS relies on the fact that freely diffusing particles, moving randomly due to Brownian motion, will produce rapid USING STATIC LIGHT SCATTERING TO MEASURE POLYMER MOLECULAR The Debye Plot. For smaller particles and for low M W polymers for which there is minimal angle dependence, it is possible to simplify the Zimm Expression such that only a single scattering angle is required. This simplification starts to break down for R g greater than about 20 nm, and should therefore be used with care. THE X-RAY DISC CENTRIFUGE Summary. Disc centrifuges fractionate particles according to both size and density, making them ideal for high-resolution particle sizing. X-Ray based detection further simplifies the process of calculating a particle size distribution from a centrifugation-based instrument, eliminating optical corrections and approximations.NANOBROOK ZETAPALS

ANALYSIS OF VIRUS PARTICLES IN MEDIA BY DYNAMIC LIGHT Introduction. Traditional visual methods of observing virus particles in solution give a snapshot of a very small sampling volume, while the technique of particle analysis using dynamic light scattering yields an ensemble average of particles present in the solutions.
