Chemical analysis on the surface of soot particles by TOF-SIMS

 

Researchers from PhLAM and PC2A laboratories published a study conducted in collaboration with researchers from ONERA and the Chevreul institute. The article is featured on the cover page of the Rapid Communication in Mass Spectrometry journal.

Scientists propose a new working method for the analysis of soot samples and the extraction of useful data from Time-Of-Flight Secondary Ion Mass Spectra (TOF-SIMS). Use of this technique in aerosol science is quite limited, especially for complex samples such as soot.

" Thanks to the new methodology, we can take advantage of the strengths of TOF-SIMS compared to L2MS such as the higher resolving power of the instrument, the improved depth resolution and the possibility of mapping the sample surface."
quote from the article

Researcher from PhLAM and PC2A laboratories are further investigating the new methodology, focusing now on the development of a database of samples. Soot samples will be collected from different flames and reaction times. The aim : to provide  ueful information on the soot nuccleation and surface growth processes.

This study was supported by the Labex CaPPA project, CPER Climibio project and european project H2020 PEMS4Nano.
