Nanoparticle content present in raw materials

RSSL were approached by a client who wanted to understand more about the nanoparticle content present in their raw materials in order to assess their response to a potential legal challenge.

Background

RSSL were approached by a client who wanted to understand more about the nanoparticle content present in their raw materials in order to assess their response to a potential legal challenge.

Approach

Analysis of the raw materials was conducted by scanning electron microscopy and revealed information about the shape, size and extent of nanomaterial present in their raw material. This was compared with data obtained by dynamic light scattering techniques to give an overview of particle size distribution.

Results

The microscopy laboratory was able to confirm the presence of nanoparticles and provide images which gave information about their shape and size. The client was then able to use this information to make an informed decision concerning their raw materials.

Summary

The portable XRF was taken to our customer’s site to map the elemental composition of different components in the preparation and production equipment.

A total of 150+ components were analysed, the analysis determining that there were three main metallic alloys:

  • Copper alloys
  • Plain steels
  • Chromium nickel stainless steels

Chromium nickel stainless steel was the most commonly used material; the analysis determining that SAE 300 series alloys were most prevalent.

A site specific database has been created which can be used as a benchmark when trying to identify and determine the provenance of subsequent contaminant metallic particles.
