Construction and the Performance Evaluation of Nanoparticle Classification Apparatus

摘要

Differential Mobility Analyzer (DMA) is an apparatus that lets particles have electrical charges in some way and classifies the particles by electrical mobility of the charged particles. This method have high accuracy of particle classification, therefore DMA is often used as particle classifier of ultrafine particles. In this study, DMA for particle size distribution measurement and collection of classified nanoparticles was constructed and its performance evaluation was carried out.
