Short summary

We investigated LLPS in four different types of SOA particles generated from α-pinene ozonolysis and α-pinene photooxidation in the absence and presence of NH₃. LLPS was observed in SOA particles produced from α-pinene ozonolysis at ~ 95.8 % RH and α-pinene ozonolysis with NH₃ at ~ 95.4 % RH. However, LLPS was not observed in SOA particles produced from α-pinene photooxidation and α-pinene photooxidation with NH₃. This result can help to more accurately predict the CCN properties of OA particles.
