Services in chemical analysis

samples samples

The  Analytical Chemistry Laboratory in the COBRA (UMR 6014, CNRS, INSA Rouen and Rouen University) provides services in the field of chemical analysis using a very large analytical equipment park.

Our team brings together researchersand engineers who have a particularly high expertise in the field of chemical analysis. We are able to provide a quick response to your expectations in many areas, including multidisciplinary fields:

  •      Identification and / or assay of organic or mineral products in different matrix: water, solvents, sludge, polymers, air ...
  •      Study of the degradation products.
  •      Identification of non-compliance product.
  •      Extraction and structural identification of unknown (extractable, unknown impurities, strange smell ...). (especially preparative HPLC)
  •      Development and validation of analytical methods (HPLC, GC, IC, GC-MS, LC-MS, ...) and transfer of the method in your laboratory.
  •      Expertise in chemical analysis
