Robust concentration measurement is an important performance metric for nanoparticle tracking analysis. Commercially available concentration standards validated by orthogonal techniques, such as TEM or sp-ICP-MS, can be used to assess concentration accuracy. However, not every laboratory has access to reference material, or requires this level of accuracy for routine verification.
In this study, NIST-traceable polystyrene latex (PSL) standards were used to evaluate dilution linearity and determine whether the ViewSizer Multi-energy NTA provides consistent concentration output across serial dilutions.
