What is it about?
Mass spectrometry with an inductively coupled plasma ionization source (ICP-MS) is used in many laboratories around the world for trace elemental analysis. We have built a data acquisition system for this apparatus that is capable of detecting single nanoparticles with microsecond time resolution and improved data quality. This helps to characterize every single particle in complex mixtures of thousands of particles and speeds up nanomaterials characterization.

Why is it important?
Single nanoparticle characterization with ICP-MS provides particle size, size distribution, and elemental composition of particles in liquid samples.
Perspectives
Instrumentation development is a lot of fun and also helps to move science forward. It is only possible with a team of excellent co-authors and a well-equipped machine shop.
