Carbonized Aramid Fiber as the Adsorbent for In-Tube Solid-Phase Microextraction to Detect Estrogens in Water Samples

<div>HPLC chromatograms of (a) samples for water in the PC bottle, spiked at 5 <i>μ</i>g/L and 10 <i>μ</i>g/L, (b) samples for tap water, spiked at 5 <i>μ</i>g/L and 10 <i>μ</i>g/L. Peaks: (1) bisphenol A (2) ethynylestradiol, (3) diethylstilbestrol, (4) hexestrol, and (5) estrone. Other conditions are the same as in Figure <a href="../fig7/">7</a>.</div>
