Abstract:Pulsed pyrolysis (Py) in combination with atmospheric pressure ionization (API) and tandem mass spectrometry was investigated as a method for detecting 1,3,5-triazine pesticide residues in agricultural matrices with minimal sample preparation. Analytes investigated were thermally stable and produced Py-API mass spectra that contained essentially only the protonated molecule. Collision-induced dissociation yielded daughter ions attributable to cleavage of the triazine ring. Limits of detection for analytes in c… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
