Vitamin Standards

Analytical and pharmaceutical reference grade standards for analysis of vitamin C/ascorbic acid present in food such as oranges

Vitamins are organic molecules and essential micronutrients required in small quantities for the proper functioning of body metabolism.

We offer a full range of fat- and water-soluble vitamins for use in various chromatography, mass spectrometry, and other analytical applications. Our standards can be used in quality control analysis of vitamin-based dietary supplements, fortified foods, cosmetics, pharmaceutical preparations, or the diagnostic testing of vitamin deficiencies. Our line of vitamin reference standards includes solution-based certified reference materials (CRMs), specially designed to minimize degradation and promote increased shelf life.

  • Vitamin A
  • Vitamin B
  • Vitamin C
  • Vitamin D
  • Vitamin E
  • Vitamin K
Related Applications
Small Molecule HPLC
Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
Mass Spectrometry
Mass spectrometry (MS) is an analytical tool used to identify compounds, determine chemical structure, and assess isotopic abundance. In MS, samples are ionized, and the resulting ions are identified based on their mass-to-charge (m/z) ratios.
Sample Preparation by Filtration
Filtration separates substances based on physical or chemical properties. Lab samples are routinely filtered before analysis to reduce sample complexity and increase analyte purity. This allows scientists to generate higher quality analytical results.
Sample Purification
A range of purification methods may be used to prepare a sample prior to downstream analysis. Purification reduces sample complexity, removes interferences, and concentrates an analyte before analysis.
QuEChERS Sample Preparation Method
QuEChERS is a ‘Quick, Easy, Cheap, Effective, Rugged and Safe’ sample cleanup method used to prepare food and agricultural samples for pesticides analysis. QuEChERS is based on the Solid Phase Extraction (SPE) technique of sample preparation.
Solid Phase Extraction (SPE)
Solid phase extraction (SPE) is a technique used for rapid, selective sample preparation and purification prior to chromatographic analysis (e.g. HPLC, GC, TLC). SPE is used to exchange sample matrices, concentrate analytes, and remove interferences and contaminants to improve data and protect the analytical column.
Solid Phase Microextraction (SPME)
Solid phase microextraction (SPME) is a solvent-free sample preparation technique that uses coated fibers to extract analytes of interest from a sample before analysis by GC or HPLC.
