Chromatograms of food additives (a), vitamins (b), and biological amines (c) obtained on 0.6 mg of CN-FSNPs/cm-poly(GMM-co-EDMA) column. For a and b, the conditions and the order of solute elution are the same as in Figs. 3a and b, respectively. For c, the conditions are the same as in Fig. 3c; solutes: 1, (±)-propranolol; 2, (±)-ephedrine; 3, (±)-phenylpropanolamine; t0, toluene.
