詳細

アプリケーション

Connect Supelclean LC-Si SPE tube (1 g/6 mL) in series to male luer outlet of Supelclean LC-Florisil SPE tube (1 g/6 mL) using an SPE Tube Adapter (57020-U). Apply up to 0.2 g transformer oil or 0.1 g waste oil to upper frit of Florisil SPE tube. Pass 5 x 2 mL isooctane through both Florisil and LC-Si SPE tubes. Oil interferences will be retained on SPE tubes whereas PCBs will elute with isooctane fractions. Collect and combine isooctane fractions using 10 mL volumetric flask. Analyze isooctane extract using GC-ECD.
