Going further with your results

We can also help you go above and beyond. Depending on your needs, branding and concerns, several complementary services can be useful, from physicochemical parameters to impurities testing and oxidative degradation without forgetting MSDS preparation .


Even with organic essential oils, some volatile pesticide residues are often present in many essential oils. They are co-distilled along the essential oil during the processing of the plant material.

Stay aware of what lies in your oil and make sure that the pesticide residue levels remain in check thanks to our powerful GC-MS/MS pesticides screening taking fully into account the effect of matrix on the results.

The test covers over 180 pesticide residues and the quantification of residues allows for comparison with USP 561 standard. Knowledge of the presence and recurrence of pesticides in your essential oils is critical in assessing a reasonable degree of tolerance to residue levels and to sort through suppliers and sources.


Ensure the quality and safety of your samples by measuring the presence via ICP-MS of several heavy metals that can be harmful for human consumption in your essential oils. The following metals will be analyzed:

  • Cadmium (Cd)
  • Lead (Pb)
  • Arsenic (As)
  • Mercury (Hg)

Ensure the quality of your oil by detecting the presence of solvents  traces.

The method is based on the USP 467 standard.

Make sure you keep an eye on aging oils, especially if they have been sitting on the shelf for a long time or have been improperly stored.

Peroxide or acid values are titrimetric methods that give indications on the state of aging of an oil.

This physico-chemical parameter allows you to control the optical activity of your sample.

You can compare the optical rotation value to international standards or to your internal specifications.
