Experts from Malvern Instruments delivered a presentation focussing on the use of on-line zeta potential measurement in water purification as part of the 87th ACS 2013 Colloid & Surface Science Symposium, held at the University of California Riverside, USA, in June 2013.
A series of new application notes posted on the Malvern Instruments website describes the quick and easy measurement of surface zeta potential using the zeta potential planar cell for the Zetasizer Nano particle characterization system.
Particle sizing methods range from simple sieving to microscopy, imaging, and laser-based techniques that measure and characterize down to molecular scale.
The measurement of polydisperse nanoparticles in the region from 10 nm to 1000 nm in liquid is a challenge. Traditional light scattering methods such as dynamic light scattering (DLS), while being excellent for monodisperse samples, tend to skew results to larger sizes (and numbers).
Micromeritics AccuPyc II 1340 and GeoPyc 1360 Pycnometers can work in tandem to help optimize process design, manufacturing, and drug product performance of pharmaceutical powders and solid dosage forms.
Micromeritics 3Flex Surface Characterization Analyzer is a fully automated, three-station instrument capable of high-throughput surface area, mesopore, and micropore analyses with superior accuracy, resolution, and data reduction.
The new Zetasizer Nano ZSP from Malvern Instruments is a high specification dynamic light scattering system that delivers unique protein characterization capabilities in a single, easy to use instrument.
Packs exceptional performance into the smallest of footprints Delivers reliable and reproducible particle size distribution measurements for both wet and dry dispersions Features dynamic range that extends from 0.01 to
