Isoprene 300ppb on B-Caryo SOA Seed
VOC/NOx 1
04.07.2008
Lights on at 09:50Short DMA is out of service
1 HALO
1.5 HALO
1.5 HALO
1.5 HALO
12:20 (2.5 HALO) lights off
During filter flushing
DMPS averaged of filling and lights on (mode has not changed)
~ 1 HALO (isoprene)
~ 1 HALO (isoprene)
High mz 30
There could be a bit of nucleationcpc number is stable and not decreasing anymore
1.75 HALO (nucleation is happening)
2.5 HALO (old mode increased from 217 to 250nm, new mode appeared)
Nucleation + wall losses(mass is not changing much)
3 HALOnucleation stopped at about 2 HALO!
3.3 HALO
Number is flat!Nucleation – wall loss = ZERO!
16:53 Lights off
Too long stopped it at 19:13
