Analysis of Artificial Food Dyes Using UltraPerformance Liquid Chromatography and an Extended Wavelength Photo Diode Array Detector

This application note presents a fast, efficient method for the analysis of food dyes in a variety of foods and beverages using the ACQUITY UPLC H-Class System with an ACQUITY UPLC Photodiode Array (PDA) extended wavelength (eλ)Detector. This 10-minute method, which includes column wash and equilibration time, allows for the simultaneous analysis of 15 artificial food dyes and selected isomers.
