We have a wide range of analytical tools and methods to assess the physical and chemical properties of your product. Especially with regard to nanoparticles (e.g. size distribution, agglomeration, dispersion stability) but also beyond. Examples for this are:
Surface activity
OECD Guideline for the testing of chemicals, No. 115: Surface Tension of Aqueous Solutions
Partition coefficient
OECD Guideline for the testing of chemicals, No. 123: Partition Coefficient (1-Octanol / Water): Slow-Stirring Method
Agglomeration
OECD Guideline for the testing of chemicals, No. 318: Dispersion Stability of Nanomaterials in Simulated Environmental Media
In addition, our selection of test organisms allows a range of standard and non-standard ecotoxicity tests (acute and chronic) in our laboratory (e.g. for REACH- and CLP- guidelines). Corresponding aquatic test systems cover both sediment and water phase exposure. This can be realized either by static, semi-static or flow-through test designs.
