Description
Summary:A central issue in the utilization of ion mobility spectrometry for chemical analysis is the proper interpretation of ion mobility spectra and the assignment of peak identities. Ion mobility spectra for contemporary drift tubes generally produce broad peaks and simple patterns without obvious details associated with structures. These features can hinder the analyses of spectra derived from mixed vapors. However, additional information from such spectra parameters and for boundaries of operation using ion mobility spectra from binary mixtures. An ion-molecule cluster ion, not obvious in traditional spectra analysis, was disclosed by deconvolution analysis and confirmed by independent ion mobility spectrometry-mass spectrometry.
