Targeted approach for qualitative screening of pesticides in salmon feed by liquid chromatography coupled to traveling-wave ion mobility/quadrupole time-of-flight mass spectrometry

摘要

The current work reports the development and validation of a qualitative screening method for 156 pesticides in Atlantic salmon feeds based on the use of ultrahigh-performance liquid chromatography (UHPLC) coupled to traveling-wave ion mobility spectrometry (TWIMS)/quadrupole time-of-flight mass spectrometry (QTOFMS). This novel hyphenation allows a straightforward estimation of the collision cross section (CCS), a physicochemical property that recently has been proposed as an additional identification point for pesticides.
