Meanwhile, measurements of zeta potential values on flat surfaces also provide critical information and save lots of time and efforts in selection of suitable substrate for particles of different properties to be attracted and kept on the surface without further aggregation. Analytical tools such as contact angle, dynamic light scattering and zeta potential have been utilized to optimize the procedure for sample preparation and to check the quality of the results.
Samples may be measured at very low or high concentration using dynamic light scattering with ‘NIBS’ optics. Cells and Cuvettes Any device for holding and measuring the sample in the instrument will generally be referred to as a. The combination of the Zetasizer Nano instrument, the computer and Zetasizer software will be referred to as the 'System'. The central idea is that micrometer sized aggregates of ZnO in powdered forms need to firstly be broken down to nanosized particles through an appropriate process to generate nanoparticle dispersion before being deposited on a flat surface for SEM observation. The Zetasizer Nano ZS is a high performance two angle particle, zeta-potential, and molecular size analyzer for the enhanced detection of aggregates and small particles. The Zetasizer Nano will either be referred to in full, as the Zetasizer, or as the ‘instrument’. Each model is available in two variants: a Blue.

Zetasizer Pro is part of the new Zetasizer Advance range which comprises of three core models: Zetasizer Lab, Zetasizer Pro, and Zetasizer Ultra. This study discusses the strategies on sample preparation to acquire images with sufficient quality for size characterization by scanning electron microscope (SEM) using two commercial ZnO nanoparticles of different surface properties as a demonstration. The Zetasizer Pro is the most versatile instrument for the measurements of molecular size, particle size, electrophoretic mobility and zeta potential.
