Mass Spectrometry Database

AROMA DB is a mass spectrometry database providing information on the molecular content of dust samples produced in various reactors (flames, dusty plasmas, laser vaporization source,…) or coming from natural samples such as meteorites.

Targeted molecules include polycyclic aromatic hydrocarbons (PAHs), carbon clusters, fullerenes and various hydrocarbons.

Data presented here are generated by the AROMA (1) (Astrochemistry Research of Organics with Molecular Analyzer) setup.

It has been developed in the framework of the Nanocosmos ERC synergy project (https://nanocosmos.iff.csic.es).

The experimental setup consists of a microprobe laser desorption ionization source and a segmented linear quadrupole ion trap connected to an orthogonal time of flight mass spectrometer.

A double bound-equivalent (DBE) method is applied to sort the detected carbonaceous molecules into families of compounds. The DBE is representative of the unsaturation level of the molecules and thus corresponds to a direct measure of their aromaticity.

It reveals in addition of PAHs, the presence of other populations such as mixed aromatic-aliphatic species, carbon clusters and fullerenes.
