ICARUS Chamber Experiment: Ng Research Group_20220718_alpha-Pinene/Limonene_Nitrate radical_Ammonium sulfate_SEQ-2

Goals: To evaluate whether or not the formation and properties of secondary organic aerosol (SOA) formed via sequential oxidation of a-pinene followed by limonene can be described as linear combinations of pure a-pinene and limonene systems. Repeat experiment. Summary: 2 uL of liquid a-pinene was injected, followed by the injection of 100 ppb of N2O5 (source of nitrate radical) at a rate of 11.3 ppb / minute. After 60 minutes since the start of N2O5 injection, 0.4 uL of liquid limonene was injected, followed by the additional injection of 40 ppb of N2O5 (source of nitrate radical) at a rate of 11.3 ppb / minute.
