HPLC Method For Analysis of Erythrosine on Newcrom BH Column

September 13, 2021

HPLC Method for Erythrosine on Newcrom BH by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Erythrosine

Erythrosine (also known as Red #3) is a fluorescent red acid dye used for food coloring, pharmaceutical dye, in printing inks, as a biological stain, and as a dental plaque disclosing agent. It is banned in the european union for health risks. It has the chemical formula C20H6I4Na2O5.

Erythrosine can be retained on HPLC mixed-mode Newcrom BH column using a mobile phase consisting of methanol (MeOH) and water with perchloric acid (HClO4) buffer. The analysis method can be UV detected at 240 or 498 nm.

Condition
Column Newcrom BH, 2.1 x 100 mm, 5 µm, 100 A, dual ended
Mobile Phase MeOH/H2O – 75/25%
Buffer HClO4 – 0.5%
Flow Rate 0.2 ml/min
Detection UV 240, 480  nm
