Isoprene 300ppb on Beta-Caryo SOA VOC/NOx

Lights on at 10:26

AMS is seeing mass only 6 min into the exp

In less than 10 min, number already peaked and mode exceeded 100nm

50min after lights on

75min ALO

75min ALO, Mass peaked

2.5 HALO

13:15 lights off

13:15 Lights off

During filter flushing

10 min after lights on (isoprene)

1 hour after lights on no increase in number nor mass

The mode also has not changed

Mode is increasing
