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.
