Abstract

A systematic study of the aerosol output was conducted from a modified commercially available Sinclair-La Mer-type monodisperse generator (TSI 3475) in the submicrometer region. The generator produces three different types of aerosols: sodium chloride, DEHS droplets condensed on NaCl nuclei and homogeneously nucleated DEHS droplets. The first two were found io be unimodal while the last one had a bimodal distribution. The aerosol droplet size distribution of the condensed aerosols was measured as a function of nuclei concentration, saturator temperature and saturator flow. It was concluded that when nuclei concentration decreases below similar to 10(6) cm(-3) homogeneous condensation is no longer suppressed and coexistence of two kinds of aerosol droplets of different size can be observed. The size distribution of all generated aerosols was measured by a scanning mobility particle sizer (SMPS). (C) 1998 Elsevier Science Ltd. All rights reserved.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
