    摘要： A method and an apparatus for determining a mobility of ions. The method includes the steps of modulating an ion beam with an ion gate which is controlled by a modulation function for generating a modulated ion beam, of guiding the modulated ion beam through a drifting region, of measuring a signal of the modulated ion beam after the modulated ion beam has passed the drifting region and of calculating a correlation of the modulation function and the signal in order to determine the mobility of the ions. The apparatus includes the ion gate, the drifting region through which the modulated ion beam is guidable, a detector by which the signal of the modulated ion beam is measurable after the modulated ion beam has passed the drifting region and a calculation unit by which the correlation of the modulation function and the signal is calculable in order to determine the mobility of the ions. An autocorrelation of the modulation function is a two-valued function.
