摘要

•First characterization of quaternary ammonium compounds (QACs) in European dust.•Detection and semi-quantification of 21 targeted QACs.•Identification of 17 additional QACs through suspect screening.•Report of reference collision cross section values (CCS) for targeted QACs.•Use of CCS-m/z trendlines for compound identification.
