Abstract:
A rectangular cylindrical drift cell is formed by bonding four resistive film layer members in which a resistive film layer having a uniform film thickness is formed on a surface of a plate member formed of an insulator of alumina or the like through a coating method or a vapor deposition. A predetermined voltage is applied from a drift voltage generator to the resistive film layers of both ends of the drift cell so that an accelerating electric field having a linear potential gradient is formed along a center axis (C) in a desolvation region and a drift region inside the drift cell. Ions are drifted by the accelerating electric field and are separated in response to the ion mobility.

Claim (Index 5):
An ion mobility analysis drift cell having a drift region, drifting ions by an accelerating electric field, formed therein, wherein the drift cell is formed by assembling a plurality of resistive film layer members in a cylindrical shape so that a resistive film layer faces an inner peripheral side using the plurality of resistive film layer members in which the resistive film layer is formed on a surface of an insulation plate member without a cylindrical closed portion.
