    experiment_goals: 'This experiment was performed to assess the reactive uptake behavior of trans beta-IEPOX that was synthesized for the experiment. Different particle inorganic compositions (mainly ammonium sulfate or AS) and different particle water content were investigated. Particles are injected into the chamber as deliquesced droplets (through a wet wall denuder) and they stabilize to their equilibrium particle liquid water content depending on their hygroscopicity.'

Local time (hh:mm),Action
13:22,Inject Na2SO4 seeds (0.06M atomizer soln) through wet wall denuder (chamber is at 70% RH)
13:42,Stop injecting seeds
14:12 (time 0),Inject IEPOX through heated bulb (60 Celsius) - although it took a while for IEPOX to be injected for unknown reasons so there may be a delay in the CIMS trace)
19:00,approximately - Stopped IEPOX injection
