Abstract:

Goals:
Observe the products (first generation: beta IEPOX) of OH oxidation; evaluate the OH LIF interference from an organic peroxide; observe ISOPOOH and its oxidation products as interferences for GC-FID/PTR-MS/others.

Summary:
The experiment went well. Long sampling periods were provided before and after oxidation to help instrument teams evaluate interferences from ISOPOOH and its products. A little over 2/3 of the ISOPOOH was reacted away using ~500 ppb of H2O2 as the OH source. Note that the ISOPOOH sample itself contained H2O2, so H2O2 was present in the bag before it was added explicitly.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
