Chamber background – brand new bag (first day of use)

CPC number dropped to <4p/cc after two fill/flush cycles!

Chamber DMPS on housing air.. The dmps has a 0.02lpm leak of clean circulation air (~3% dilution)

Chamber housing air

11:01 cpc number dropping below 1p/cc with no spikes!

Zero mass!

During final flush

DMPS software crashed! Right after lights on

1h ALO: still not much happening

Just after 1h ALO: nucleation started

Chamber diagnostics

3h ALO: almost no change in NOx and O3 initial concentrations so far!

4h ALO: still no O3 production and not much change in NOx concentration

The excess flow meter is not connected
