Applications:

UV-Vis Spectrum of Riboflavin (Vitamin B2)

September 16, 2024
UV-Vis Spectrum of Riboflavin. Absorption Maxima: 224 nm, 268 nm, 370 nm, 446 nm.

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

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

August 22, 2008

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.

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.

HPLC Method for Separation of Vitamins Group B such as Nicotinic Acid, Pyridoxine, Niacinamide, Pantothenic Acid, Riboflavin on Obelisc N Column

August 22, 2008

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.
