HPLC Separation of Two Vitamins: Different Polarity – Isocratic Methods

Primesep B and B2 columns separate Vitamins C (ascorbic acid) and B2 (riboflavin) with tunable selectivity. Peak order reversal is exhibited on these two columns with the same mobile phases due to their different polarity. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and either formic or acetic acid (HOAc) with UV detection at 250 nm.

Condition

Column Primesep B, Primesep B2 , 3.2×50 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer Formic Acid, Acetic Acid
Flow Rate 0.5 ml/min
Detection UV, 250 nm
