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 3):
An ion mobility spectrometer in which ions originating from a sample component are introduced into a drift region and separated from each other according to mobilities of the ions by being made to move through the drift region, and the separated ions are either detected or further sent to a subsequent analyzing-detecting section, the ion mobility spectrometer comprising:\n a) a housing including an insulating member in which an inner space having a rectangular columnar shape penetrating through the insulating member is formed, where at least a portion of the inner space forms the drift region, and a ratio of a long side to a short side of a rectangular cross section orthogonal to an axis of the inner space is greater than one; b) a resistive layer formed at least on a surface of two mutually opposing faces containing two long sides of the rectangular cross section of the inner space having a rectangular columnar shape penetrating through the insulating member, for creating an electric field for driving ions within the inner space of the housing; and c) a shutter gate located within the inner space of the housing in order to introduce ions in a pulsed form into the drift region formed by the at least a portion of the inner space of the housing, where the shutter gate includes a frame body shaped like a rectangular loop having a rectangular opening and a plurality of electrically conductive wires stretched parallel to a short side of the rectangular opening, with a ratio of a long side to a short side of the rectangular opening being greater than one.
