Analytical Testing

Analytical Testing

All Unibar proprietary, branded ingredients are subjected to extensive analytical testing, much of which is performed at the CU Varkey Centre for Research and Quality Assurance — a highly equipped technology center — to ensure identity, composition, limits on contaminants, and lack of adulteration.

Identity Tests

  • UV spectrophotometry (to confirm identity of source material)

Composition Tests

  • HPLC (to confirm composition and activity)

Contaminant Tests

  • Microbiological assays (to ensure limits on microbiological contaminants)
  • ICP-MS (to ensure limits on heavy metals)
  • Gas chromatography (to ensure limits on pesticide and solvent residues)
  • Affinity chromatography (to ensure limits on aflatoxins)

Adulteration Tests

  • HPLC (to detect economic or pharmaceutical adulteration)
