High Performance Liquid Chromatography (HPLC) Method for Analysis of Sodium ascorbyl phosphate .
Sodium Ascorbyl Phosphate is a popular, more mild, form of Vitamin C with the chemical formula C6H6Na3O9P . It is found in a variety of dermatology products and used for its antioxidant properties.
Sodium ascorbyl phosphate can be retained and analyzed on a mixed-mode Newcrom BH column with a mobile phase consisting of water, Acetonitrile (MeCN), and either Sulfuric acid (H2SO4) or Phosphoric acid (H3PO4) as the ionic modifier. This analytical method can be UV detected at 238 nm with high resolution and peak symmetry.
