Aerosol generation by spark discharge
S Schwyn,E Garwin,A Schmidt-Ott +2 more
TL;DR: In this article, an aerosol generator for generating particles of any desired mobility, equivalent radius, and conducting material has been developed, where particles are formed by electrode atomization in a spark discharge, and a high yield of charged particles enables generation of high concentration (> 10' cmm3) monodisperse aerosols using electrostatic classification.

The chemical response of the photo-electric aerosol sensor (PAS) to different aerosol systems
TL;DR: In this article, a comparative study of the response of a photo-electric sensor to different PAH aerosol systems is presented, showing that an analytically useful response is only obtained as long as a monolayer coating is not exceeded.

In situ measurement of adsorption and condensation of a polyaromatic hydrocarbon on ultrafine C particles by means of photoemission
Heinz Burtscher,A. Schmidt-Ott +1 more
TL;DR: In this paper, a screen-type diffusion battery is shown to be applicable for sub-monolayer detection on 7-8 nm particles if the penetration is as small as 1% and a combination of this method with in situ near-UV photoemission from Perylenecoated C particles leads to a clear distinction between adsorption and condensation.
