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 8):
An ion mobility analyzer that uses the ion mobility analysis drift cell according to  claim 5 , comprising:\n a) an ion source that generates ions derived from a sample; b) a voltage generator that applies a predetermined voltage to both ends of a resistive film layer of an inner peripheral surface of the drift cell to form an accelerating electric field inside the cylindrical ion mobility analysis drift cell; and c) a shutter gate that is disposed at an ion incident side end portion of the ion mobility analysis drift cell or an inner space of the drift cell and allows the passage of ions generated by the ion source only for a predetermined period to be sent to a drift region where the accelerating electric field is formed inside the drift cell, wherein the ion mobility analyzer detects ions separated in response to ion mobility while passing through the drift region inside the ion mobility analysis drift cell or further sends the ions to a subsequent analysis and detection unit.
