The X-ray Disc Centrifuge – A Unique Particle Sizing Technique
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. This has been shown to be especially relevant for metal particles and metal oxide, which […]

Introducing the Sample Filtration System
The sample filtration system from Brookhaven Instruments, the BI-SFS, is a fast and convenient method of cleaning all light scattering samples. Using Teflon tubing and non-reactive components, the system is compatible with almost all filtration needs. Its modular design allows users to change pump heads and speeds to tackle virtually any application. Dust in samples […]

Zeta potential measurement of limestone in seawater by Phase Analysis Light Scattering
Abstract Measurements of limestone in 100% seawater (1.15M ionic strength), 50% seawater, and 25% seawater were conducted on the Brookhaven Instruments NanoBrook ZetaPALS. Below is the procedure for preparing these samples as well as the measurement parameters used in their analyses. Introduction Zeta Potential is relatively easy to measure in cases of high charge and […]

Using Uncertainty Analysis to Optimize GPC System Performance (from Boston ACS meeting, 2010)
Introduction GPC when coupled with Static Light Scattering (SLS) is a fairly modern and powerful technique for determining absolute molecular weight values without the need to rely on traditional column calibration. In GPC-SLS the signal intensity levels rather than elution times are evaluated quantitatively. In addition, unlike in polymer standard calibration, details of the accurate […]

Molecular Weight of PVP with the BI-MwA
Library Polyvinylpyrrolidone (PVP) a Molecular Weight Determination with the BI-MwA Polyvinylpyrrolidone (PVP) is a polar molecule and is used in a wide variety of applications. For example, since it simply passes through humans, it is a binder in pharmaceutical tablets. Because PVP binds to polar molecules quite well, it is also used as a paper […]
