Short summary
LLPS, efflorescence and deliquescence of aerosol particles can be observed visually and determined quantitatively. Different LLPS mechanisms may dominate successively in mixed organic–inorganic particles. The formation of more concentrated inorganic inclusions may cause secondary LLPS. Furthermore, high inorganic factions may result in an inorganic salt crust enclosing the separated organic phases.
