• A possible endocrine disrupter, bisphenol A (BPA) in environmental water, was analyzed using conventional HPLC coupled with an electrochemical detector (ECD). The ECD-HPLC method realized a much easier and reliable pre-treatment process compared with the usual GC/MS method. In this study, we utilized a column-switching system for the analysis of BPA in environmental water. We also utilized a commercial membrane for the concentration of environmental water. The quantification limit observed in this study was 5 ng/l (ppt). The column switching system utilizing high-pressure 6 port valves realized 0.7 ppt as the detection limit, and the reproducibility observed using a 1 ppt standard sample of BPA was 2.7% (RSD). In addition, although BPA was found to somehow be decomposed in environmental water, we found a storage method of BPA.
