Preferred Label : absolute preconcentration;
Detailed label : absolute preconcentration in trace analysis;
IUPAC definition : An operation (process) as the result of which microcomponents are transferred from
the sample of larger mass into the sample of smaller mass, so that the concentration
of the microcomponents is increased. Examples include the decrease in solvent volume
during distillation or evaporation, and the transfer of microcomponents from an aqueous
solution into a smaller volume of organic solvent by extraction.;
