Real time monitoring of chemical reactions has become a key step in industrial processes due to constantly increasing demands on product performance and environmental compatibility. In contrast to spectroscopic methods that usually require sample pretreatment, mass spectrometry (MS) has been proven as a robust method for multicomponent analysis. As an especially demanding reaction process, we here report successfully on the entirely contactless conduction and interrogation of a chemical reaction inside an acoustically levitated microliter droplet of reaction mixture. The approach represents a proof of concept study for fast reaction optimization approaches with minimal resource consumption. The sampling is done by repeated laser desorption of small fractions of the droplets volume spread over the timescale of the reaction process.
