Nanomaterial Testing


Nanomaterials can be found in traditional applications and forward-looking technologies. For example, nanomaterials offer efficient solutions for the energy sector and can help us achieve ambitious climate targets. We help the chemical industry to register these materials (under REACH) by conducting important studies on nano properties.

Our focus here is on studies that do not need to be performed for other chemicals, such as determining particle size distribution, dispersion stability, and solubility rates of nanomaterials.

Highly qualified study directors
Fast study conduction
Successful registration


Our offer includes nanospecific investigations and studies: physico-chemical studies (e.g. particle size distribution and volume specific surface area), E-Fate studies on dispersion stability and dissolution rate, as well as various ecotoxicological studies under GLP!


According to your needs, we offer a range of analytical methods for adequate characterization and quantification of your product.


Nanomaterials require additional information for REACH registration, including nanospecific physico-chemical parameters such as surface area (OECD TG 124) and particle size distribution (OECD TG 125).

Environmental Fate

It is important to know the behavior of nanomaterials in environmentally relevant media, especially agglomeration and dissolution, as it is important for planning ecotoxicology and toxicology studies.


Ecotoxicological studies of nanomaterials, especially algae and daphnia, accompanied by the necessary characterization and quantification of the test item in the test medium.

Studies for the registration of nanomaterials under REACH

Particle size distribution, dispersion stability (OECD TG 318), dissolution rate…

what distinguishes nEcoTox?


Particle size distribution

We determine the particle size distribution using TEM or SEM images for REACH registration.


Dissolution Rate

We determine for them the solubility rate of nanomaterials according to OECD GD 29 and 318


Dispersion Stability

We determine the dispersion stability of nanomaterials according to OECD TG 318



We actively participate in interlaboratory comparisons, e.g. within the NanoHarmony project
