Comparison of two stationary phases for the separation of five selected polyphenols

In this study, a conventional TEKNOKROMA, Tr-015605 TRACER EXTRASIL ODS2 (25 cm × 0.4 cm, i.d. 5 μm) column and a new stationary phase TEKNOKROMA, Tr-010065 Mediterranea sea18 (15 cm × 0.4 cm, i.d. 3 μm) were compared for the separation of five phenolic compounds. ivity, performance characteristics, analysis time and method validation were reported for both columns. A better sensitivity and performance were achieved with the novel chromatographic support. In addition the total analysis time was significantly reduced. thod was applied to the determination of the selected polyphenols in commercial available white wines. LC–MS was used as a confirmatory technique.
