HPLC Method for Analysis of Allura Red, Sunset Yellow, Tartrazine in Mountain Dew Live Wire at 2 Wavelengths

Sunset Yellow FCF, also known as Orange Yellow S, C.I. 15985, or Yellow 6, is a petroleum-derived orange azo dye. When in powder form, it is Reddish-orange, but when dissolved in water, the liquid becomes bright yellow. The dye is banned or restricted in Norway, Finland and Sweden. Obelisc N is a column with very polar characteristics. It contains embedded acidic and basic ionizable groups and can retain Sunset Yellow. The method is LC/MS and UV compatible and can be used as a general approach for analyzing similar compounds.

Application Column

Obelisc N

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
