A sensitive and selective method for the determination of flumorph residues in vegetables and fruits by HPLC-ESI-MS/MS

► In this study we develop a sensitive and selective method based on LC-MS/MS for the determination of flumorph residues in vegetables and fruits. ► We study the conversion rule between flumorph (Z) and flumorph (E). ► We confirm chromatographic behavior of flumorph (Z) and flumorph (E).
