Abstract

In this study the mass spectra of fourteen carbamate pesticides, obtained with desorption chemical ionisation (DCI) and flow injection (FIA)-particle beam (PB)-ammonia positive chemical ionisation (PCI)-mass spectrometry (MS), are compared. The mass spectra from the FIA-PB-PCI-MS experiments exhibit higher relative abundances for fragment ions. The influence of the ion source pressure and temperature on the ion abundances under ammonia positive chemical ionisation conditions was studied. The results indicate that thermal degradation of the carbamate pesticides takes place in the FIA-PB-MS system. In addition, the [M + NH
