Abstract
A number of techniques has been developed to study particles suspended in a carrier gas, that is an aerosol. These methods allow for example to determine number concentration, size and mass of the particles, or yield information on morphology and chemistry of the particles. Some are also feasible to study adsorption and desorption processes either by monitoring chemical changes on the particle surface (by photoelectron emission) or by determining the change in particle size, which can be done on a monolayer-scale resolution. Examples are given of how information on shape and structure of the particles can be obtained by measuring the mass versus diameter, thus obtaining a fractal-like dimension. These techniques can be very useful to investigate nanometer sized particles, often in real time on a time scale in the order of seconds or even less.
