Characterisation of diesel exhaust emission using GC×GC coupled to variable ionisation mass spectrometry

Mohammed. S. Alam, Christopher. P. Stark & Roy. M. Harrison

Samples were collected from the exhaust of a diesel engine using both filter and impaction. GC×GC-ToF-MS was exploited to characterise the composition of SVOC from the exhaust emission. Using variable electron energy ionisation the positioning and degree of branching of isomeric hydrocarbon compounds within many homologous series’ are identified and presented.
