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

July 16, 2009

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.

Condition

Column Obelisc N , 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer AmAc pH 4.0
Flow Rate 1.0 ml/min
Detection ELSD

 

Description

Class of Compounds
Acid, Vitamin B₆, Hydrophobic, Ionizable
Analyzing Compounds Citric acid, ascorbic acid and EDTA

Application Column

Obelisc N

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.

Select options
Application Analytes:
Ascorbic Acid
EDTA (Ethylenediaminetetraacetic Acid)
Vitamin C

Application Detection:

HPLC Separation of Vitamin C and Vitamin B2

November 21, 2006

Vitamin C (ascorbic acid) and Vitamin B2 (riboflavin) are water-soluble vitamins that are not stored in the body and must be replaced each day. Primesep D easily resolves Vitamins C and B2 and the elution order can be reversed by adjusting acetonitrile and acetic acid concentrations in the mobile phase. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and acetic acid (AcOH) and UV detection at 250 nm.

Condition

Column Primesep D , 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer Acetic Acid
Flow Rate 1.0 ml/min

HPLC Separation and Retention of Vitamins in Mixed-Mode on Primesep B2

May 5, 2005

Primesep B and B2 columns separate Vitamins C (ascorbic acid) and B2 (riboflavin) with tunable selectivity. Both columns allow peak order reversal by simply changing the acetonitrile concentration in the mobile phase. Vitamin B2 is especially sensitive to acetonitrile concentration. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and either trifluoroacetic acid (TFA) or acetic acid (HOAc) with UV detection at 250 nm.

Condition

Column Primesep B2, 3.2×50 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
