摘要: Abstract In an improved generator of the Sinclair-La Mer type monodisperse droplets di-2-ethylhexyl sebacate (DEHS) in 0·08–4 ,μm dia. range were produced by condensation DEHS-vapour on sodium chloride nuclei a stream pure nitrogen. The electrical heating NaCl-coated platinum wire. Their size and concentration depend nitrogen flow rate current as proved electron microscopy monitoring concentration. final distributions DEHS aerosols evaluated optical spectrometry. geometric standard deviation varied between 1·035 1·06.
