Workstation no. 7 – Particle analysis

35.00

The particle analyser (Zetasizer Nano ZS, Malvern Panalytical) utilizes optical measurement techniques based on light scattering to measure a size distribution (in a range of 0.3 nm to 10 µm), and a zeta potential (in a range of -500 mV to 500 mV) of the diamond particles suspended in liquids. Both quantities are crucial in production, disaggregation, and functionalization of the nanodiamonds. The measurement of the size distribution enables to quickly control parameters and verify results of the ball milling and/or the ultrasonic treatment, while the value of the zeta potential indicates the colloidal stability of the particles in a specific dispersion medium, and provides better understanding of the processes of charge transfer occurring due to the modification of the nanodiamonds’ surface.

The price is for one hour of operational and do not including materials.
