Abstract: A high-performance liquid chromatographic(HPLC)-tandem mass spectrometry(MS)method was developed
to analysis four pesticides residue, including hexaflumuron, teflubenzuron, lurfenuron and flufenoxuron. Sample
analyte enrichment was performed by a C18 column. Identification and quantification were carried out using atmospheric
pressure chemical ionization mode and multiple reaction monitoring(MRM). The limits of detection for
hexaflumuron, teflubenzuron, lurfenuron and flufenoxuron were 0.02, 0.02, 0.02 and 0.02 mg/kg. In the ranger of 0.05-
0.5 mg/kg, the recovery were 75.2-84.5%.
Key words: high-performance liquid chromatography-trandem mass spectrometry; residues; hexaflumuron;
teflubenzuron; lurfenuron; flufenoxuron
