Single Particle Methods

Single particle methods reduce the complexity of an aerosol distribution.

Techniques applied to study single particles allow measurements to be made in the absence of interactions with other droplets and under regulated gas-phase conditions. The microphysical processes that influence the dynamics of aerosol become resolvable and measurements of processes, such as evaporation and condensation, lead to a more in-depth analysis of mass and heat transport kinetics and the thermodynamic equilibrium state of aerosol. Single particle studies have been conducted with free-falling droplets or those which are contactlessly levitated, using either an acoustic trap, optical forces or an electric field.
