Making drugs safe – identifying the quantities of individual species in a sample.

The testing of trace metals in drug products, drug substances, biologics, dietary supplements, and medical devices is critical to determine the toxicity of a material and to predict its interactions with other compounds.

Metals like arsenic (As), mercury (Hg), selenium (Se) and chromium (Cr) have very different toxicities depending on their oxidation state. Speciation analysis enables you to determine whether your product has toxic forms of these elements or if it is safe for distribution.

Exova’s speciation programs include:

  • Determining organic vs inorganic arsenic in algae and seaweed supplements
  • Measuring inorganic selenium in organoselenium pharmaceuticals
  • Verifying the absence of As(V) in As(III) raw materials
  • Performing analysis of highly toxic hexavalent chromium in environmental samples and nutritional supplements.

We provide advanced metals speciation analysis that cover diverse fields including environmental samples (air, soil, and water), raw materials testing, pharmaceuticals, and nutritional supplements.

State-of-the-art Ion and Liquid Chromatography, coupled with ICP-MS or with post-column reaction techniques, allow us to provide high-quality results.
