Simultaneous solvent extraction and quantification of eleven amine compounds related to Chemical Weapon Convention in soils via hydrophilic interaction liquid chromatography-tandem mass spectrometry

•A novel SE formulation for simultaneous extraction of amine analytes from soils.•Single and simple SE method with high extraction efficiencies for 11 amine analytes.•Good separation of 11 analytes on HILIC column from environmental soil matrices.•Simultaneous quantification of 11 CWC-related amine compounds in four-type soils.•Lowest LODs over those of all previous LC-MS/MS methods.
