The application of the thermal energy analyser to the analysis of nitrosamines and organic nitrates

Abstract

The thermal energy analyser (TEA) has been used as a detector to analyse five different types of samples of nitrosamines and organic nitrates. Results are presented for the analysis of nitrosodimethylamine in aqueous samples using capillary gas chromatography, with a detection limit of less than 20 ppb. Total nitrosamine content of personal hygiene products was determined using chemical denitrosation coupled to the TEA, with a similar lower limit. Nitroglycerin and pentaerythritoltetranitrate were analysed qualitatively in explosives residues. Attempts were made to quantify nitrosodiethanolamine in a dye, and nitroglycerin in blood, and the initial findings are presented.
