Abstrakt: Hollow fibre-liquid phase microextraction (HF-LPME) was applied for rapid and efficient extraction of basic drugs from dried blood spots (DBS). Basic drugs from DBS were first extracted into 10 mM NaOH solution, which acted as the HF-LPME donor solution, and simultaneously the neutralized drugs were transferred across the HF and preconcentrated in 10 mM HCl acceptor solution inside the HF lumen. Mixture (1:1, v:v) of 1-ethyl-2-nitrobenzene and dihexyl ether was used for impregnation of the porous HF membrane. Analytes in the acceptor solution were injected directly from the HF into capillary electrophoresis instrument for further separation, detection and quantification. Repeatability of the hyphenated analytical system ranged from 9.8 to 13.8 % (RSD) and enrichment factors of 52 – 78 were obtained for model basic drugs spiked to DBS extracts at a concentration level of 0.1 mg/L.
