Determination of nicotine and its metabolites accumulated in fish tissue using hydrophilic interaction liquid chromatography coupled with tandem mass spectrometry

“…Food samples were pretreated by a combination of acetonitrile LLE and dispersive solid‐phase extraction (dSPE) to remove impurities in the matrix. Over the past few years, QuEChERS has been used for preparation in the analysis of insecticides in fruits , vegetables , and other kinds of food products .
