摘要：Methods and devices are provided for calibrating the mobility axis of an ionmobility spectrum and determining the mobility characteristic of ion species from an ion

mobility spectrum, in particular for calibrating the drift time axis of an ion mobilityspectrum acquired by a drift type ion mobility spectrometer (IMS). An ion mobilityspectrometer uses an ion source that comprises a first ionization region which is fluidlycoupled to a sample source, a second ionization region which is spatially separated fromthe first ionization region and fluidly coupled to a calibrant reservoir, and electricalmeans for controlling the transfer of sample ions from the first region into the secondionization region or into a third region of the ion source wherein the third region is fluidlycoupled to the first and second ionization region and located closer to a mobilityanalyzer than the first and second ionization region.
