| Description
| - A simple on-line method for simultaneous determination of some oestrogens including oestriol (E3), norethisterone (NORE), ethynylestradiol (EE2), D-norgestrel (NORG) and bisphenol A (BPA), in environmental liquid samples was developed by coupling in-tube solid phase microextraction (in-tube SPME) to high-performance liquid chromatography with diode array (DAD) and fluorescence (FLD) detectors. Two capillary chromatographic columns (Supel-Q (TM) and Carboxen (TM) 1006 porous layer open tubular) were selected to develop this method. To achieve optimum extraction performance, several parameters were investigated including number of draw/eject cycles and the sample volume for each of the columns. Reproducibility was satisfactory for inter-and intra-day precision, yielding % RSDs of less than 10% and 7.6%, respectively. Limits of detection (LODs) and quantification (LOQs) for the proposed method using a DAD detector were achieved in the ranges of 0.04-0.63 ng mL(-1) and 0.12-1.9 ng mL(-1), depending of the capillary column used. Fluorescence detection improved these parameters for E3, BPA and EE2, obtaining LODs of 0.005-0.03 ng mL(-1) and LOQs of 0.015-0.08 ng mL(-1) using Supel-Q and LODs of 0.01-0.015 ng mL(-1) and LOQs of 0.025-0.04 ng mL(-1) using Carboxen. The proposed method was successfully applied to spiked environmental waters obtaining recoveries greater than 80%.
