Parabens possess antibacterial and antifungal properties and are therefore widely used in pharmaceutical and cosmetic industries as preservatives in products. Parabens and benzoic acid can be baseline separated in a short time frame using Primesep B2 reverse-phase HPLC column with a simple mobile phase of water, acetonitrile (ACN, MeCN) and phosphoric acid of 0.1% as buffer. UV detection at 210nm.

Condition 2

Column Primesep B2, 4.6x150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer H3PO4
Flow Rate 1.0 ml/min
Detection UV, 210 nm
