An artifact-free method for the analysis of nitrosamines in diesel engine crankcase emissions was developed. The method involved trapping volatile nitrosamines in either a pH 4 phosphate-citrate buffer solution or ThermoSorb/N cartridge, followed by extraction of the traps with appropriate solvents, concentration, and analysis of the concentrate on a gas chromatograph and/or high-pressure liquid chromatograph interfaced to a TEA Analyzer. Validation of the reliability of the method included the intentional addition of amines and/or nitogen oxides. Confirmation of the identity of the nitrosamines was by high-resolution mass spectrometry. Detection limits, based on a 60-L sample, were 0.1 ..mu..g/m/sup 3/ for N-nitrosodimethylamine and 0.16 ..mu..g/m/sup 3/ for N-nitrosomorpholine.
