Figure 3.7 Test for trace metal ions on the surface of octadecyl-bonded silica gel. Column A, 5 pm octadecyl-bonded silica gel, 15 cm x 4.6 mm i.d. B, octadecyl-bonded silica gel, 15 cm x 4.6 mm i.d. C, octadecyl-bonded 10 pm silica gel, 30 cm x 4.0 mm i.d. eluent, 50% aqueous acetonitrile flow rate, 1 ml min-1 temperature, ambient detection, UV 220 nm (the scales of A, B, and C are not the same) sample, 8-hydroxyquinoline. Columns, A, metal ion free B, low proportion of metal ions C, high level of metal ions. Figure 3.7 Test for trace metal ions on the surface of octadecyl-bonded silica gel.
