<p><P>PROBLEM TO BE SOLVED: To realize a compact ionic mobility spectrometer with high selectivity. <P>SOLUTION: Air flow is generated inside a drift tube 5 headed from a detector 18 side toward an ion source side, and a first area a1 with a flow speed increasing in a flowing direction, a second area a2 with a constant flow, and a third area a3 with a flow speed decreasing are arranged in turn from an upstream side toward a downstream side of the air flow. Light irradiation mechanisms 51, 52 are provided at the second area for dissociating ion. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
