摘要
A drift tube ion mobility spectrometry sample introduction scheme allows introduction of a sample packet at ground voltages. The sample packet of ionized particles is captured by subjecting particles within a defined region to an electric field at an elevated voltage. The ionized particles in the captured packet then migrate through the drift tube down the voltage gradient according to their electrical mobility. The particles are directed to a high sensitivity detector, such as a condensation particle counter (CPC), for detection.
