Ultra-high speed separation of food additives in a soft drink

In this application note, the usefulness of an X-PressPak V-C (2.0 mm I.D. x 50 mm L.) packed with 2 μm diameter packing material for the ultra-high speed separation of food additives was examined. A 4λ−UV detector was used for the simultaneous monitoring of these additives at four different wavelengths. The results were examined to determine whether the performance of the column and chromatography system exceeds those of conventional HPLC.
