摘要：The present invention relates to methods and devices for calibrating themobility axis of an ion mobility spectrum and for determining the mobility characteristicof ion species from an ion mobility spectrum, in particular for calibrating the drift time

axis of an ion mobility spectrum acquired by a drift type ion mobility spectrometer (IMS).It provides an ion mobility spectrometer characterized in that an ion source comprises afirst ionization region (11a) which is fluidly coupled to a sample source, a secondionization region (11b) which is spatially separated from the first ionization region andfluidly coupled to a calibrant reservoir (30), and electrical means for controlling thetransfer of sample ions from the first region into the second ionization region or into athird region of the ion source wherein the third region is fluidly coupled to the first andsecond ionization region and located closer to a mobility analyzer than the first andsecond ionization region.
