Description
Aggregates are a common particle type in the air - irregular particles built up by smaller primaries/monomers. One aim of the work is to present and test methods, experimental and theoretical, to characterize aggregates in the transition regime with regards to properties relevant for toxicological and nano-technological applications. Furthermore, we characterize and compare the properties of the gold-aggregates generated by three generators. The generators tested were a high temperature evaporation furnace (HT) and two spark discharge generators, one commercially available (SDGP) and a custom built (SDGC). The SDGC has been applied in several studies relevant for toxicology.
For the characterization both online instrumentation, such as differential mobility analyzer and aerosol particle mass analyzer coupled in series (DMA-APM) and differential mobility particle sizer (DMPS), and off-line transmission electron microscopy techniques were used. Except from size, number, mass, and morphology, the surface area is a property of special interest. Based on the experimental data, the total surface ar
