Zeta potential and particle size measurement instrument range extended.
Beckman Coulter have extended their DelsaNano range of DLS based zeta potential and particle size measurement systems. A new zeta potential only (DelsaNano Z), and high sensitivity combined zeta potential and sizing (DelsaNano HC) models are now available. The DelsaNano range uses patented optics to enable it to measure most samples without the need to dilute, and also to provide zeta potential measurements on surfaces and films. Particle sizes of small particles/molecules such as Fullerene (C60) down to 0.6 nanometres can be measured. Concentrations from ~40 % down to less than 1ppm can be measured.
In conjunction with the Auto Titrator AT, additive or pH profiles can be measured using the easy to use SOP driven software.
We are happy to run a couple of your typical samples to show you the quality of data the DelsaNano can provide.
