Catalytic Processes in Materials Science

Sticky subject: An N2 stream forms bubbles inside bulk viscous liquids, which create an aerosol sample through a microjetting mechanism (see picture). This aerosol is then analyzed by extractive electrospray ionization (EESI) mass spectrometry (MS). EESI-MS reveals the molecular composition of complex liquids and the kinetics of ongoing processes occurring in the highly viscous liquids without any sample pretreatment.
