One advantage that the nanoparticle tracking analysis technique has over other particle sizing techniques is the ability to resolve multiple peaks in a sample, allowing for multi-modal size and concentration analysis of each population in a sample. Other techniques, like laser diffraction or dynamic light scattering, will often struggle when the sizes of different populations in a sample start to get too close, and are instead measured as a single peak.
In this application note, a mixture of 100 nm, 200 nm, and 400nm PSL standards was created to investigate the ability of the ViewSizer 1000 Nanoparticle Tracking Analyzer to resolve multiple peaks of close size in a sample.
