Mix Plants: Exp

09:45 Pre-exp (during filling)

09:56 flush before last

10:11 During final flush

10:18 it seems like a nucleation event during the final flush

10:18 new nucleation + background modes – total mass 0.03ug/m3 (full bag)

10:32 Filling via plant chamber started at 10:20

11:31 Lights on after 38ppb O3 injection which lead to immediate nucleation

40min HALO

2h40min ALO still nothing really happening!

4h20m ALO 0.03ug/m3 nothing is really happening yet!

7h8min ALO we injected 50ppb Limonene and got an instant nucleation of particles/cc and 33 ug/m3!! Bag had MORE than enough oxidants and the plant chamber didn’t deliver enough VOCs!

Up to 50 ug/m3 5 min later!
