ELECTRODE RING FOR ION MOBILITY SPECTROMETER, ION TRANSFER TUBE AND ION MOBILITY SPECTROMETER

摘要

The present disclosure provides an electrode ring for an ion mobility spectrometer, an ion transfer tube and an ion mobility spectrometer. Wherein, the electrode ring has an outer edge thickness larger than its inner edge thickness in an axial direction. Through the present disclosure, in the structure of the electrode ring, the uniformity of the electric filed inside the transfer tube can be significantly improved. In the present disclosure, the smooth ion transfer zone inside the transfer tube can be enlarged. The ion transfer tube formed of electrode rings each having an inner edge thickness the same as the outer edge thickness in the axial direction apparently has poorer uniformity of electrode field than the ion transfer tube formed of electrode rings each having the same outer edge thickness but an inner edger thickness smaller than the outer edge thickness in the axial direction.
