Our new smog chamber. There are two collapsible 5 m^3 reactors inside the chamber.
We have acquired a Thermo Q-Exactive mass spectrometry. This instrument has a high-field Orbitrap that combines a resolution of up to 140,000 with high scan speed. The new chamber and Q-Exactive will be used for our secondary organic aerosol research projects.

Different roles of water in secondary organic aerosol formation from toluene and isoprene
Short Summary: In this work, the opposite effects of relative humidity (RH) on secondary organic aerosol (SOA) formation from toluene and isoprene were observed and have been well explained in terms of various experimental data and model simulations. The increase of SOA from toluene under humid conditions is mainly contributed by aqueous reactions of water soluble products, whereas SOA formation from isoprene-NO2 irradiations is controlled by stable Criegee intermediates that are greatly influenced by water.
