Determination of polycyclic aromatic hydrocarbons in water by capillary solid-phase microextraction coupled to high performance liquid chromatography

Abstract

Capillary solid-phase microextraction, a sample preparation technique, was established and applied to the, determination of polycyclic aromatic hydrocarbons in, water by coupling to high-performance liquid chromatography (HPLC) The analytes were extracted onto the polymer film of a piece of gas chromatographic capillary and desorpted into HPLC injector by a small amount of organic solvent. The limits of detection for anthracene, fluoranthene and 1, 2-benzanthracene were 0.9 mug/L, 0.7 mug/L and 0.1 mug/L respectively. Good reproducibility was obtained with RSD ranging from 5.1% to 6.3% for 10 mug/L spiked samples (n=7).
