A new application note, available on the Malvern Instruments website, describes how the new ZEN1010 high concentration zeta potential cell for the company’s Zetasizer Nano particle characterisation system, overcomes a major hurdle in measuring the zeta potential of high concentration samples.
Taking the notoriously difficult-to-measure titanium dioxide as an example, the authors describe experimental work that demonstrates accurate and reliable zeta potential measurement of concentrated, turbid suspensions. This ability to measure the zeta potential of more concentrated samples than has previously been possible is thanks to the reduced optical path length of the new ZEN1010 cell, and has applications for a very wide range of materials.
