Determination of crop protection products and contaminants is not easy. Hundreds of pesticides are on the market and they are used on hundreds of different commodities.

Primoris offers the analysis of a broad range of commodities and investigates in research to be an expert in the determination of pesticides and contaminants on special, more complex commodities like:  

  • Oil containing seeds and vegetable oils
  • Plant extracts such as medicinal preparations and essential oils
  • Animal products such as milk, eggs, meat, fat, cheese, honey
  • Spices
  • Sugar crops
  • Tobacco
  • Tea, coffee and cacao
  • Others

Legislation

For a lot of those more complex commodities, no specific legislation is actually in place. In order to make a correct interpretation of the analysis result, we follow the general MRL rules described in the pesticide EU-MRLs and active substances.

Analyses

Based on the wide variety of analyses that we offer, we are able to analyse a big number of more complex matrices.

Certified by

The group of complex matrices is a very heterogeneous group of matrices (like milk, spices, sugar crops, oil containing seeds, ...) so there is no specific certification for complex matrices in general.

Please contact us if you have questions about complex matrices, as we believe that our role goes beyond laboratory analysis.
