HPLC Method for Analysis of Allura Red (FD&C Red 40, E129) on a BIST A Column

November 30, 2022

Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies

HPLC Method for Analysis of Allura  Red (FD&C Red 40, E129) on a BIST A Column
HPLC Method for Analysis of Allura Red (FD&C Red 40, E129) on BIST A Column by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analyses of Allura Red (FD&C Red 40, E129)

Allura Red (FD&C Red 40,  E129) is a popular red synthetic dye used in a wide variety of food products. Using SIELC’s newly introduced BIST™ method, Allura Red 1, which ionizes in water, can be retained on a negatively-charged, cation-exchange BIST™ A column. There are two keys to this retention method: 1) a multi-charged, positive buffer, such as N,N,N’,N’-Tetramethyl-1,3-propanediamine (TMDAP), which acts as a bridge, linking the negatively-charged Acid Red 1 analytes to the negatively-charged column surface and 2) a mobile phase consisting mostly of organic solvent (such as MeCN) to minimize the formation of a solvation layer around the charged analytes. Using this new and unique analysis method, Allura Red can be retained and UV detected at 500 nm.

Analyzing CompoundsAllura Red (FD&C Red 40, E129)

Application Column

BIST A

BIST™ columns offer a unique and effective way to achieve separations that were traditionally challenging or even impossible with other HPLC columns. With the use of a special mobile phase, these ion exchange columns provide very strong retention for analytes with the same charge polarity as the stationary phase, unlocking new chromatography applications. What makes BIST™ columns stand out is their proprietary surface chemistry, which results in superior selectivity, resolution, and sensitivity. These columns offer a simple, efficient solution for a variety of analytical challenges, making them an excellent choice for researchers and analysts across many different fields.

Brilliant Blue FCF, also known as Blue 1, is an compound classified as a triarylmethane dye. Dry, it has the appearance of a light-blue powder, but when dissolved in water, turns deeper blue. Allura Red AC, also known as FD&C Red No. 40, is a red azo dye that is the most commonly used red dye in the United States. It is used anywhere from tattoos to children’s’ medications to drinks and food. If used in food it also has the E number E129. Allura red is sold as a dark red sodium salt, but when dissolved in water, the solution appears orange-red.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.
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 and separate dyes with perfect peak shape using a mobile phase of methanol (MeOH) and water with sulfuric acid (H2SO4) to facilitate ion-exchange. UV detection at 400nm.
