Nanoparticle Characterisation

Nanoparticle Characterisation 

NPL can provide analysis for nanoparticles within a wide variety of media. An expanding range of properties can be reliably determined for powders (e.g. BET surface area analysis, Surface Chemistry), suspensions in various liquid media (e.g. Zeta Potential) and as aerosols created from either powder or liquid suspension (e.g. aerodynamic size distribution).

For powders and suspensions, the nanoparticle characterisation expertise at NPL comes from several departments using techniques such as SEM, TEM, Dynamic Light Scattering, XPS, SIMS and Zeta Potential. Standardised nanoparticle dispersion protocols are used to create suspensions from powder samples, with new protocols being developed as required. The media can vary from simple aqueous to biological media.

NPL's dedicated Airborne Nanoparticle Metrology Laboratory offers services supporting the measurement and characterisation of nanoparticles in the aerosol phase. The use of state of the art instrumentation for nanoparticle generation and detection provides a high degree of confidence in the measurements we make.

Our services are being progressively developed and assessed for ISO 17025 compliance to ensure that they are of the highest possible quality.
