The AROMA (Astrochemical Research of Organics using Molecular Analyzer) experimental set-up has seen the first light by showing nice peaks of C60 and its 13C isomers in Toulouse. The AROMA main purpose is to analyze the molecular content of cosmic dust particles, more specifically stardust analogues that will be produced in the Nanocosmos Stardust machine in Madrid.
The central part of AROMA arrived from Greece at the University Toulouse III – Paul Sabatier (France) on September 18th 2015. The construction was performed by Fasmatech, a young Greek company, following requirements from the IRAP scientific team. It consists of a linear ion trap combined with a high-resolution time of flight mass spectrometer. After months of development, the setup was delivered on time in Toulouse at the laboratory LCAR. Only two days later, a first light could be obtained. The laser desorption ionization of fullerene showed nice peaks of C60 and its 13C isomers. Further optimization of the signal was performed on the next days and this will continue in the coming weeks. The IRAP team is also working on combining the two steps laser desorption laser ionization source to the instrument. The objective is to analyze the molecular organic phase at a micron scale.
