Malvern Panalytical approached project partner NPL with their, now released, Zetasizer Ultra. This has improved capability to measure nanoparticle concentration due to the combination of multi-angle DLS (MADLS) and adaptive correlation. As one of the industrial collaborators of the NPL-led EMPIR Innanopart project, Malvern Panalytical had knowledge of the expertise within the consortium and wanted… Read More

Caterina Minelli of NPL’s Surface Technology group is leading the Versailles Project on Advanced Materials and Standards (VAMAS) TWA34 (Nanoparticle populations) Project 10 interlaboratory comparison on the measurement of number concentration of nanoparticles. The study will run in parallel with the BIPM CCQM-P194 pilot study (led by LGC) on the same materials. The materials chosen… Read More
