0.3 ml samples are introduced to the viewing unit using a disposable syringe and, enhanced by a near perfect black background, particles appear individually as point-scatterers moving under Brownian motion.
Polydisperse and multimodal systems are instantly recognisable and quantifiable, as are agglomerates and contaminants.
The image analysis Nanoparticle Tracking Analysis (NTA) software suite allows the user to automatically track and size nanoparticles on an individual basis. Results are displayed as a frequency size distribution graph and output to spreadsheet. Video clips of images can also be retained.
