Abstract :
The chromatographic determination of trace amounts of aromatic hydrocarbons in model solutions based on distilled water was developed. New methods of dispersive microliquid extraction were used. Extra small volume of extractant (10 mcl) and centrifuge usage allows to prepare samples for chromatographic analysis quickly (5-10 min). The proposed procedure and concentration conditions have a great potential in analysis of objects containing trace amounts of impurities.
