High performance clean-up
① 90 mL of hexane for eluting dioxins and PCBs: i. Trapping dioxins and NO-PCBs on carbon ii. Trapping MO and NDL-PCBs on alumina
② Open the pinch valve
③ Elution PCBs with 1.5 ml of toluene
④ Close the pinch valve and open the other pinch valve
⑤ Elution Dioxins with 1 ml of toluene
