We analyzed
all samples, except PLA 3, using ultrahigh performance LC-QTOF-MS/MS
with an Acquity UPLC Waters liquid chromatography system coupled to
a SYNAPT G2-S mass spectrometer (both Waters Norge, Oslo, Norway).
The analytical method has been described in the study of Zimmermann
et al.,30 (link),31 (link) and a brief description as well as information
about the data analysis and compound identification can be found in
the Supporting Information (Nontarget Chemical
Analysis).
