Abstract

Preconcentration of aqueous solution of aromatic compounds was successfully carried out with an extraction capillary packed with a bundle of polymer-coated filaments. The extracted analytes were sequentially eluted with a flow of pure water using programmed temperature elevation of the extraction capillary. The results clearly suggest that the polymer-coated fiber-packed capillary could be employed as a sample preparation medium for the analysis of aqueous matrices. The fraction of interest could be transferred to conventional microcolumn liquid chromatography (LC) allowing a heart cutting analysis of aqueous matrices. Stability of the fiber-packed capillary was confirmed with pure water as the mobile phase at elevated temperatures.
