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
