Ionic mobility analyzer and method for analyzing vapor samples

摘要

PROBLEM TO BE SOLVED: To provide an ion mobility analyzer having an ionization unit having improved reliability and reproducibility. An ion mobility analyzer 100 for analyzing a vapor sample 102 includes a multi-ring ion source 104 that receives the vapor sample, and the multi-ring ion source includes a series of rings. Each ring of the multi-ring ion source contains an ionized layer on its inner surface and charges at least a portion of the vapor sample to produce an ionized vapor sample. [Selection diagram] Fig. 1
