preconcentration

analytical procedure to increase the concentration of analytes in the analytical solution in comparison with that present in the original sample. The techniques used include cryofocussing, gas-solid extraction, solid-phase extraction (SPE), solid-phase microextrraction (SPME), solvent extraction and evaporation.
