Development of an On-Column Trace Enrichment Method for the Determination of Sub-<i>μ</i>g/L Bisphenol A in Bottled Water by RP-HPLC with Fluorescent Detection

<div>Typical chromatogram obtained for 1.20 <i>μ</i>g/L of (a) bisphenol S, (b) bisphenol F, and (c) BPA. The sample was loaded for 3 minutes at 2.0 mL/min, followed by chromatographic elution at 1.0 mL/min with 50% acetonitrile/water. Fluorescence detection: Ex<i>λ</i> = 274 nm and Em<i>λ</i> = 314 nm.</div>
