(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
Laboratory experiments were carried out to study Schiff-base condensation reactions between amines and formaldehyde that occur on inlet lines of emission monitoring instruments. Primary amines and formaldehyde were found ...

CLIMIT project no. 208122
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
We apply a high-resolution chemical transport model (GEOS-Chem CTM) with updated treatment of volatile organic compounds (VOCs) and a comprehensive suite of airborne datasets over North America to (i) characterize the VOC ...
