Abstract: A system for separating certain ions from an ion beam in a mass spectrometer. A magnetic or electrostatic field is applied at an angle to the ion beam, causing the ions to disperse according to their mass to charge ratio. The ions are dispersed enough to allow certain ions to be blocked and removed from the beam using a physical stop. A subsequent plurality of fields is then applied to reform the beam and adjust its direction and dispersion.

Abstract: An electrically heatable hollow-body furnace with a secondary surface on which an analyte of a sample can be condensed prior to being atomized. The furnace is constructed in two sections which are capable of being electrically heated independently of one another. The secondary surface is defined by a surface of one of the sections. A process for atomizing an analyte of a sample to be examined, utilizing the device according to the following steps: introducing the sample into a hollow-body furnace having a secondary surface, condensing the analyte on the secondary surface and atomizing the analyte.
