Increased Throughput for the Determination of Synthetic Dyes in Beverages Using HRes Fast-LC Technology

In this application note, an HRes fast-LC method was developed for the determination of typical dyes found in aperitif beverages, and was compared with a conventional chromatographic method. Two aperitif beverages were analyzed using the HRes fast-LC method. This application note demonstrates how HRes fast-LC using sub-3 μm particle column technology can be used to accelerate dye QA/QC methods. The use of photo diode array (PDA) detection in combination with HRes technology provides added confidence in peak identification for method development in complex beverage formulations.
