NANOPARTICLE SIZE MEASUREMENT BY NANOPARTICLE TRACKING ANALYSIS (NTA) METHOD

Junjie Liu, Wenge Zhang
Abstract:
Nanoparticle Tracking Analysis (NTA) is a newly developed method, and in the measure process, there are several factors and parameters which have significant effect on the accuracy of final mean particle size result. In this paper, we analysis the effect of sample concentration, camera parameters (shutter, gain and duration) and analysis parameter (threshold) on the obtained NTA results. Based on the work, appropriate methods about sample preparation and parameters settings in video capturing and analysis process are developed by measuring a polystyrene sample with nominal value of 80 nm.
