Sticky subject : An N 2 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.
