HPLC Isocratic Method for Analysis of Ascorbic Acid and Sodium Metabisulfite on Primesep SB Column
August 22, 2023
HPLC Method for Analysis of Ascorbic Acid, Sodium metabisulfite on Primesep SB by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Ascorbic Acid, Sodium metabisulfite
*The metabisulfite ion (S2O52−) is hydrolyzed to bisulfite (HSO3−) in water. Sodium metabisulfite is a white crystalline or powder solid. It has many uses, but some of it’s more prominent are: as the source of SO2 in wine, as a bleaching agent in the production of Coconut cream, and added to anesthetic solutions to prevent oxidation to improve the shelf life of the solution. Ascorbic is found naturally in citrus fruits and many vegetables. As a medication, it is used to prevent or treat low levels of vitamin C, since it is that vitamin. Vitamin C is needed to maintain the health of skin, cartilage, teeth, bone, and blood vessels. Ascorbic Acid and Sodium Metabisulfite can be separated, retained, and analyzed on a Primesep SB mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a phosphoric acid (H3PO4) buffer. This analysis method can be detected in the UV 270 nm.

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.
