Abstract
This article presents a method to apply a conventional differential electrical mobility analyzer (DMA) in combination with a condensation nuclei counter (CNC) to the quasi-real-time measurement of particle size distributions and total concentrations from very highly concentrated aerosol sources such as during TiO 2 flame synthesis. Accuracy and error sources of this approach are discussed. Additionally, ways are shown to augment the DMA-derived mobility size information with the help of geometric particle parameters (e.g., size and number of primary particles within an aggregate) determined off-line by scanning electron microscopy.
