Evaluating the multiple benefits offered by ion mobility-mass spectrometry in oil and petroleum analysis

摘要: Ion mobility-mass spectrometry is starting to be considered as a useful tool in the deconvolution of complex oil and petroleum samples. While ultrahigh resolution mass incumbent technology this field, ion mobility offers complementary information related species size shape, also ability resolve structural isomers. In work, sample resins portion Saturates, Aromatics, Resins, Asphaltenes (SARA) fractions crude was analysed using an orthogonal acceleration quadrupole time-of-flight spectrometer (oa-QToF MS) that incorporates travelling wave (TWIMS) region. The data were compared with previously acquired Fourier transform cyclotron resonance (FT-ICR various nitrogen containing families identified. processed typical way for industry; use high exact coupled provide enhanced examined. Double bond equivalence (DBE) carbon number groups identified patterns data, which demonstrated utility discovering relationships within sample. calibrate cell generate sizes detected ions recognised potentially having particular value implementation conversion or hydrotreatment processes industry.
