Abstract:
An inner space having a rectangular cross section with the long-side-to-short-side ratio greater than one is formed in a housing ( 20 A,  20 B) made of an insulator. The inner space forms a desolvation region ( 4 ) and a drift region ( 5 ). A shutter gate ( 22 ) located within the inner space also has a long-side-to-short-side ratio greater than one. A number of conductive wires are stretched over the opening of the gate to form grid electrodes. This configuration allows the shutter gate ( 22 ) to have a large opening area while using short conductive wires to decrease the amount of deflection of the wires due to the potential difference between the wires and thereby prevent the adjacent wires from coming in contact with each other as well as prevent the electric field from being disordered due to an operation for allowing ions to pass through or blocking ions. Since the desolvation region ( 4 ) and drift region ( 5 ) have a rectangular cross section, the Reynolds number is low, and a diffusion gas forms a laminar flow. Thus, the analysis accuracy and resolving power will also be improved.

Claim (Index 10):
The ion mobility spectrometer according to  claim 3 , further comprising:\n an ion source located on an outside of one of open-ended faces of the inner space of the housing, for ionizing a sample component at a plurality of locations along an extending direction of the long side of the rectangular open-ended face.
