Electron impact (EI) using ionizing electrons of different kinetic energies, ammonia and methane positive chemical ionization (PCI) and plasma desorption (PD) mass spectrometry were used for the analysis of aryl pesticides of the carbamate and phenylurea families. Under PD conditions, competitive fo
