Abstract

This manuscript reports an inter-laboratory comparison evaluation of a transmission electron microscopy (TEM) protocol for measuring the particle size distribution of discrete, spheroidal nanoparticles. The study was focused on automated image capture and automated particle analysis. RM8012 gold nanoparticles (30 nm nominal diameter) were measured for area-equivalent diameter distributions by eight laboratories. Statistical analysis was used to: 1) assess the data quality without using reference models, 2) determine reference model parameters for different models and fitting methods, and 3) assess the measurement uncertainty of a parameter by using its standard error value.
