Short summary
Oxidation flow reactors (OFRs) are promising tools of studying atmospheric oxidation processes. Elevated concentrations of both OH and non-OH oxidants in OFRs leave room for speculation that non-OH chemistry can play a major role. Through systematic modeling, we find conditions where non-OH VOC fate is significant and show that, in most field studies of SOA using OFRs, non-OH VOC fate in OFRs was insignificant. We also provide guidelines helping OFR users avoid significant non-OH VOC oxidation.
