TL;DR: Evidence for oligomer formation for SOA from both precursors was given by an increasing abundance of compounds with a high molecular weight and by an increase thermal stability with increasing aging time.

TL;DR: In this paper, water-soluble organic matter (WSM) extracts were extracted in MilliQ-water, and, in a second step, solid phase extraction was used to isolate the less hydrophilic fraction (ISOM) of the WSOM from remaining inorganic salts and "most" hyrophilic organic matter, which allowed ISOM which constitutes the major fraction of WSOM to be isolated from ambient aerosols and investigated in pure form.

TL;DR: In this paper, the particle number size distribution (diameter D = 18-750 nm) and number concentration N (D > 10 nm) were measured on a continuous basis during an extended field campaign at a high-alpine site (Jungfraujoch; 3580 m asl, Switzerland) from March 1997 to May 1998.

TL;DR: In this article, the chemical nature of the bulk of water soluble organic compounds in fine atmospheric aerosol collected during summer 1998 at the Jungfraujoch, Switzerland (3580 m asl) is characterised.

TL;DR: In this paper, a thermal method for the determination of ambient organic carbon (OC) and elemental carbon (EC) concentrations in carbonaceous samples was further developed, which was applied to samples obtained with an aethalometer from an ongoing campaign at the high-alpine research station Jungfraujoch.
