HPLC Determination of Erioglaucine on Newcrom BH Column

HPLC.cloud View on hplc.cloud   Erioglaucine, more commonly known as Brilliant Blue FCF, is a synthetic coloring dye used in many industries as a colorant for foods, medications, cosmetics, etc. It is a multi-charged molecule and generally has poor peak shape on reverse-phase HPLC columns. By using a Newcrom BH mixed-mode column with both ion-exchange and hydrophobic properties, erioglaucine can be retained and exhibits great peak shape by using a mobile phase of methanol (MeOH) and water with sulfuric acid as buffer. UV detection at 625nm.
