Abstract
Investigations into Aromatic Hydrocarbons and N and S Heterocompounds thereof by Means of Electron Attachment Mass Spectrometry Aromatic compounds as well as their nitrogen and sulphur heterocompounds with molecular weight M>100 are investigated using negative ions from electron attachment mass spectrometry. Mass spectra of aromatic compounds produce molecular peaks as basepeaks predominantly. In general, the type of the basepeak of heterocompounds and its detection sensitivity depends more on the chemical structure of the compound than on the type of the heteroatom. The relative detection sensitivity of the molecular peak in dependence of an amount of sample is a linear function on a log-log scale. Addition of argon extends this linear dependence towards larger sample amounts. For quantitative analysis, however, the measurements must be performed at a fixed ion source pressure.Keywords
