Abstract

An ion mobility detector (10) for measuring the mobility of ions incorporating a cylindrical shutter grid (18) concentric with a cylindrical collector (20) having an electric field radially therebetween. The invention overcomes the problem of recombination at exposed sidewalls of the drift region. The invention further overcomes the problem of sensitivity by maximizing the area of the shutter grid (18) and collector (20).
