HPLC Separation of Vitamin C, Vitamin Group B, and Related Impurities

2008-08-22

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.

Obelisc N

SIELC has developed the mixed-mode Obelisc™ columns to be the first commercially available columns with Liquid Separation Cell technology (LiSC™). This cost effective duo can replace multiple HPLC columns such as 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.

HILIC Separation of Vitamins Group B

2008-08-22

Separation of vitamins group B is achieved on Obelisc N column in HILIC mixed-mode. Vitamins of this group are different in polarity and ionic properties. Retention and separation is achieved by optimization of amount of ACN, buffer and buffer pH. Combination of UV and ELSD detection is used to monitor HPLC separation. B vitamins are water-soluble vitamins that play an important role in cell metabolism. Supplements containing all six are generally referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific name of each vitamin. This method can be used to analyze individual B vitamins as well as vitamin B complex. Isolation of impurities as well as degradation products is possible by preparative chromatography.

HPLC Separation of Vitamin C and Vitamin B2

2006-11-21

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.

Separation and Retention of Vitamins in Mixed-Mode HPLC

2005-05-05

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.
