Concentrating of samples is widely used in combination with solid phase extraction (SPE) in analyses of environmental samples (determination of polycyclic aromatic hydrocarbons, biphenyls, chlorophenols, pesticides, etc.). It is used method of concentrating dissolved samples by solvent evaporation using introduction of controlled gas flow above the level of the solution with temperature control.
