Experiment Set
Diesel SOA for liquid-liquid phase separation and viscosity within secondary organic aerosol generated from diesel fuel vapors

Goals
Make Diesel SOA to study viscosity and liquid-liquid phase separation of SOA from the photooxidation of diesel vapors.

Summary
Prepare SOA for diesel study from diesel #2 and OH at low relative humidity and high NOx.
