N-CBZ-Norvaline

Fig. 2-5. Examples showing the eomplementary separations on glyeopeptide CSPs. (A) Separation of N-CBZ-norvaline on vaneomyein (left) and teieoplanin (right). The mobile phase was methanol 1 % triethylammonium aeetate (20/80 v/v) pH 4.1. (B) Separation of warfarin on teieoplanin (left) and vaneomyein (right) CSPs. The mobile phase was aeetonitrile 1 % triethylammonium aeetate (10/90 v/v) pH 4.1. (C) Separation of naproxen on teieoplanin (left) and ristoeetin A (right). The mobile phase was methanol 0.1 % triethylammonium aeetate (30/70 v/v) pH 4.1. All eolumns were 250 x 4.6 mm i.d. The flow rate for all the separations was 1 mL min at ambient temperature (23 °C).
