Short summary
Oxidation flow reactors (OFRs) have been increasingly used to study atmospheric chemistry at high NO. We show that it is very difficult to obtain high-NO chemistry (in terms of RO2 fate) in OFRs by initial NO injection. Past OFR studies with combustion sources generally had too-high precursor and NOx concentrations that caused several types of experimental artifacts. A strong dilution (× 100 or larger) may be needed for such experiments to avoid undesired chemistry.
