Analytical method development and validation

Our analytical park includes equipment such as LC-HRMS, LC-MS/MS, GC-MS/MS, ion chromatography (IC), UV-Visible spectrophotometer and Size-exclusion chromatography. The RRS team has also access to a nuclear magnetic resonance spectrometer (NMR) and ICP-AES.

Thanks to its analytical platform, RRS develops analytical methods for simple organic substance (pure substance, monomer…) and complex organic substance such as polymer.

Based on its expertise and its Good Laboratory Practice quality system (Area 8 : Analytical and clinical chemistry testing) RRS is able to work on a wide range of matrices such as water, liquid from process, solvent, effluents, biological fluids, air, soil, sediments and all plant and animal matrices.

RRS offers developed and validated analytical method

Stability - Storage

Do you need stability/storage study? RRS offers assistance in analytical method development and analysis of your product – accelerated and long term studies.

Certificate of analysis and substance characterization

RRS offers services of chemical organic substance identification. The Certificate of Analysis gives you information on the quality of your substance (main components and impurities) thus as the absolute purity of the active substance and the impurities.

REACH,  Specific case — Annexe VI

RRS offers:

  • Each substance composition
    • Degree of purity (%)
    • Nature of impurities, including isomers and by-products
    • Percentage of (significant) main impurities
    • Nature and order of magnitude (e.g. ppm) of any additives
    • Spectral data (UV, IR, NMR, Mass Spectrum)
    • High pressure liquid or gas chromatography
    • Description of analytical methods or the appropriate bibliographical references for the identification of the substance and, where appropriate, for the identification of impurities and additives.



In case your substance needs a detailed chemical analysis ; RRS offers a « screening » analysis.
