English. A new multi-residue analytical method has been proposed for the analysis of trace levels of N-methyl carbamates and some of their main metabolites. The residues are extracted from the examined sample (apple) with CH2Cl2, then purified with gel permeation chromatography and determined with reversed-phase high-performance liquid chromatography with post-column reaction and fluorescence detection. Recovery, uncertainty and precision were also evaluated

I residui degli antiparassitari sono estratti dal campione con diclorometano in presenza di terra di diatomea, purificati in cromatografia a permeazione di gel, quindi analizzati per cromatografia ad alta pressione a fase inversa previa derivatizzazione post colonna e rivelatore a fluorescenza
