Abstract
The requisite process chambers for field desorption ionization are annularly arranged and cooperate with electrodes on the inside. Individual electrodes are cyclically and in steps juxtaposed to the process chambers so that the various steps are simultaneously carried out on different electrodes. After a cycle, all electrodes have faced all of the chambers. Alternatively, a single wire is segmentwise placed adjacent to the chambers. The process steps are, in each instance: activating the electrode (or a wire segment); depositing an analyzing substance; ionization; and cleaning.
