Analytical services

Do you want to assay food or ingredient components?
Looking to characterize your product and highlight its properties?
Are you searching for a specific analysis that can’t be found in a private lab?


With our state-of-the-art techniques and sophisticated methods, INFA’s analytical laboratories make it easy to discover, characterize, and assay many different families of compounds. Our experts are able to analyze a lot of different compounds such as sugars, organic acids, amino acids, antioxidants, polyphenols, flavonoids, anthocyanins and others.


INAF’s analytical services can analyze and characterize your products. By determining their composition and highlighting their qualities we can help you promote your functional foods and ingredients.

Areas of expertise

  • Determination of bioactive compounds in foods and vegetable matrices
  • Determination of bioactive compounds and their metabolites in biological matrices (tissues, organs, urine, serum, plasma)

What we offer

Our studies and analyses are performed rapidly with quality as our top priority. Depending on your needs, we can also develop the analytical method, produce comprehensive analyses reports signed by a member of Ordre des chimistes du Québec, and provide support in interpreting results. Below is a list of some of the analyses we routinely supply.

 

Plant matrices

  • Antioxidant potential (ORAC, BL-DMAC, European Pharmacopoeia)
  • Total polyphenols by spectrophotometry (Folin-Ciocalteu)
  • Polyphenol profiles by UPLC-MS (list of compounds to be determined according to the samples)
  • HPLC  profiles :
    • Anthocyanins
    • Proanthocyanidins (PAC's)
    • Sugars
    • Organic acids

 Biological matrices (tissues, organs, urine, serum, plasma)

  • Polyphenols and their metabolites
  • Short chain fatty acids

Analytical services team

Our team is composed of specialized professors, a chemist and highly qualified and experienced research professionals trained in the chemistry of natural substances and biotechnology. 

Facilities

Our analytical services laboratory has a large array of cutting-edge equipment and procedures, including:

  • Ultra high performance chromatography coupled with tandem mass spectrometry (UPLC-MS/MS)
  • Liquid chromatography (HPLC and UHPLC)
  • Gas chromatography (GC-FID and GC-MS)
