| Abstract | We investigated the ion mobility spectra of 8 isomeric nitrogenous aromatic compounds using various ionization techniques in order to estimate the influence of structural differences on the ionization pathways and drift behavior. The positive ion mobility spectra of benzylamine, 3 different methylanilines and 4 different dimethylpyridines with a molecular weight of 107 amu were measured using 63Ni ionization, corona discharge ionization and photoionization. A distinct influence of molecular structure on the ion mobility spectra can be identified depending on the ionization technique applied. The methods of atmospheric-pressure chemical ionization (corona discharge ionization and 63Ni ionization) provide product ion peaks with nearly identical reduced mobility values for the compounds investigated. Although the spectra consist of up to three product ion peaks, their intensities in ion mobility spectra vary depending on the ionization technique used. The difficult interpreted spectra obtained by photoionization exhibit considerable differences for the compounds investigated. |
