HPLC Determination of Tartrazine (Yellow 5) on Newcrom BH Column

Separation type: Liquid Chromatography Mixed-mode

 


Tartrazine is a yellow food coloring agent. It’s a trisodium salt, and like many multi-charged molecules tends to exhibit significant tailing using reverse-phase HPLC columns. By using a mixed-mode column, specifically designed in mind for multiple charges, Newcrom BH can retain tartrazine with perfect peak shape using a mobile phase of methanol (MeOH) and water with sulfuric acid (H2SO4) to facilitate ion-exchange. UV detection at 430nm.

Application Column

Newcrom BH

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
