Summary
A HPLC method for the simultaneous determination of benzophenones is described. The seven compounds studied were separated on a Hypersil ODS C18 (25 cm×4.6 mm i.d.) using acetonitrile-methanol-water (30:30:40,v/v/v) as mobile phase at 1.0 mL min−1 and detected at 286 nm. The results obtained were in good agreement with those obtained by differential pulse voltammetry.
