Stationary phases Prontosil C18 AQ (similar, Fs = 7.7), Genesis AQ (reference) and Platinum EPS C18 (different, Ag —58). Conditions columns, 15cm x 4.6mm i.d. mobile phase, 1 mlmin potassium dihydrogen phosphate pH 2.7 in water-methanol (96.7 3.3) temperature, 6O C UV detector, 210nm. Peaks 1—nicotine 2 = benzylamine 3 = procainamide 4 = terbutaline 5 —salbutamol 6 —phenol.
