Abstract
The number concentrations of nominal 100 nm, 200 nm and 500 nm diameter, fluorescently-labeled polystyrene nanosphere suspensions were measured using seven different techniques. Diameter values were also measured where possible. The diameter values were found to agree within 20%, but the number concentration values differed by as much as a factor of two. Accuracy and reproducibility related with the different techniques are discussed with the goal of establishing number concentration standards for sub-micrometer particles.Citation
