"Nanoparticle Tracking Analyzer for hydrodynamic Particle Size, Zeta Potential and Concentration...With ZetaView® individual particle tracking, classical micro-electrophoresis and Brownian motion are presented as modern analysis tools. Auto-alignment and auto-focusing make the “Seeing is Believing” principle user friendly. By sub-volume scanning robust results of zeta potential and size histograms are derived from thousands of particles. In addition, particle concentrations can be determined by video frame assessment counting. Sample cell handling is reduced to a few handholds." [www.particle-metrix.de]
