Abstract
Embodiments of the present invention provide an air dryer for an ion mobility spectrometer, comprising a heating element used to heat a thermal conduction device, thereby heating the desiccant. Embodiments of the present invention further provide a regeneration method, by which the operation mode of the ion mobility spectrometer may be switched, so that during a non-working time of the ion mobility spectrometer, the desiccant is heated and thereby regenerated. With the present invention, the desiccant is avoided from being regularly replaced, thereby improving the performance and increasing the service life of the dryer. Regeneration of the desiccant is performed by making full use of the non-working time of the ion mobility spectrometer without affecting normal operation of instrument.
