In this study, the results of an experimental study by surface ionization mass spectrometry of the insecticide acetamiprid (N1-methyl-N1-[(6-chloro-3-pyridyl)methyl]-N2-cyanacetamidine) in an oxidized tungsten thermo-emitter were reported for the first time. Surface ionization mass-spectra of the substance showed quasi-molecular ion [M-H]+ lines as well as fragment ion [M-R]+ lines. Based on the experimental data obtained so far, the formation laws of the surface ionization mass-spectrum were considered, and the decomposition schemes of the molecules formed on the surface of the heated thermo-emitter were proposed.
