Abstract
An ion source includes a nebulizer and a target, with the nebulizer being arranged and adapted to emit, in use, a stream of analyte droplets which are caused to impact upon the target and to ionize analyte to form a plurality of analyte ions. The target comprises a pin or rod which is mounted off-set from a rotating shaft. The target is rotated or translated in use and follows an eccentric path such that the relative position between the nebulizer and target varies as the target is rotated or translated.
