Brookhaven Instruments reports that its ZetaPlus has been specially designed to determine the zeta potential of particles and droplets in liquid suspension. It is seen as a vital instrument for research in the pigments industry, said to combine ease-of-use with value for money.
According to Brookhaven the ZetaPlus gets around the problem of electro-osmosis, making it much simpler to use. The company states that you do not have to adjust the optical alignments before taking measurements and you can use low-cost disposable sample cells instead of the complex, delicate cells normally required.
Clear, easy-to-use WindowsTM software is thought to make the ZetaPlus an ideal instrument for limitless applications. Features claimed include the ability to plot zeta potential against any defined parameter, for example, additive concentration or pH, and choose between single or automatically repeated measurements. The ZetaPlus can also be controlled by an external or built-in computer, depending on space constraints.
Sub-micron particle size distribution analysis is available as an option, allowing complete characterisation of colloidal systems to monitor and control such properties as dispersion, flocculation and stability.
