Nanomaterial analysis and Nanoparticle testing

We have further specialized in nanoparticle testing associated with registration of materials in the European Union and in relation to European Commission regulations. Therefore we have grouped the crucial analysis techniques like BET surface area, Electron Microscopy, Dynamic Light Scattering and Differential Centrifugal Sedimentation in one business unit. In this way we can optimally work for our customers in the area of nanoparticle testing. These nanomaterial testing techniques are documented in the Nanodefine methods manual and in the JRC framework that are closely related to the European Commission Recommendation on the definition of nanomaterials (2011/696/EU). Defining a material as a nanomaterial by experimental efforts is not as simple as it seems. The definition, which holds from 2011, is still valid nowadays. The definition’s boundary is that 50% or more of the particles in the number size distribution need to have an external dimension in the size range of 1 – 100 nm.

These nanoparticle testing activities are needed in the more strict REACH registrations. Meanwhile, the huge variety of documents available on the EC website can make it hard to identify a clear research path for nanoparticle assessment. As Delft Solids Solutions we would like to facilitate this process and as such we can surely assist you in your nanomaterial testing needs.

We are currently structuring this part of our website and dedicated nanoparticles and nanomaterial pages can be found in the sub-menu on this page of nanomaterial testing.
