Ascorbic acid is a naturally occurring vitamin with antioxidative properties. Ascorbic acid and its sodium, potassium and calcium salts are used as preservatives in many products. Acsorbic acid (Vitamin C) is part of a multi-vitamin composition and various supplements. Ascorbic acid was analyzed on the core-shell mixed-mode column with excellent peak shape and retention control. This method can be used for analysis of vitamin C in different compositions and complex matrices. It can be monitored by UV, ELSD or MS. Coresep SB stationary phase is always positively charged and in case of analysis of biofluids, protein components will come before ascorbic acid.

Application Name : HPLC Analysis of Ascorbic Acid on Core-Shell mixed-Mode Column

Column Name : Coresep SB Columns

Analytes : Ascorbic Acid

Citric acid, ascorbic acid and EDTA are commonly used in food and pharmaceutical industry as preservatives. These compounds are very polar in nature. They are weak organic acids with limited UV activity. Retention and separation is achieved on HILIC mixed-mode Obelisc N column. All three compounds are retained by combination of strong HILIC and strong anion-exchange mechanisms. Separation can be monitored by ELSD, LC/MS, UV or Corona CAD. In contrast to other HILIC column, Obelisc N has two ionizable groups basic and acidic which provide ion-exchange interaction in addition to hydrophilic interaction. This allows to use less acetonitrile for HILIC separation.

Application Name : HILIC Separation of Common Preservatives – Citric Acid, Ascorbic Acid and EDTA

Column Name : Obelisc N Columns

Analytes : Citric acid, Ascorbic Acid, EDTA (Ethylenediaminetetraacetic Acid)

Vitamin C (ascorbic acid) and Vitamins Group B are separated on Obelisc N mixed-mode column. Method can be used in quantitation and determination of polar vitamins in various formulations and dietary supplements. HPLC method can be based on UV, Evaporative Light Scattering Detection (ESLD), RI or MS detection. Effect of sample matrix can be eliminated by changing mobile phase conditions. Buffer concentration, buffer pH and amount of ACN will affect every vitamin differently due to difference in polar and ionic properties.
