    • The manufacturing of a furnace for electro-thermal atomization of samples for spectroscopical purposes having a cavity for the accommodation of sample is simplified and improved. To this end, the furnace consists of two halves which are joined along a separating plane intersecting the cavity. The furnace is made of graphite and provided with a layer of pyrolytic graphite. A platform for the accommodation of the sample is integral with one of the halves. A method for the production of such a furnace comprises the method steps: (a) producing two blank parts which engage each other with planar surfaces; (b) machining the two blank parts in common so that a cavity intersected by the plane of the planar surfaces is generated and each of the blank parts forms one half of the furnace; (c) separating the two halves of the furnace which were produced in this way; (d) coating the halves of the furnace separately, the inner surfaces of the cavity forming outer surfaces of each of the two halves of the furnace; and (e) joining the halves of the furnace, generated in this way, to a furnace. There is also a method described for decreasing the refuse in the manufacturing of the furnaces.

    • An atomic emission spectrometer for multi-element measurement of elements in a sample comprises an apparatus to atomize the sample and to excite the atoms for emitting characteristic spectral lines, a dispersion device which generates a spectrum of the light emitted by the atoms in a focal plane, and a plurality of semiconductor photodetectors, each of which is exposed to one of said characteristic spectral lines. A plurality of semiconductor photodetectors which are exposed to different spectral lines of different intensities of the line spectrum emitted by the atoms of the respective element are utilized so as to achieve a sufficiently large dynamic range for each element to be measured. For measuring each element, an evaluating circuit is arranged to select one semiconductor photodetector for which the intensity of the associated spectral line lies within a part of the measuring range of the semiconductor photodetector which is as favorable as possible.

    • A device for electrothermal atomization of samples for spectroscopic purposes with a furnace body made of graphite, designed such that electrical current can be passed through, and a pot-shaped sample receptacle which is separated from the furnace body and projects into a lateral aperture of the furnace body comprises a driving device by which the sample receptacle is movable into and out of thermal contact with the furnace body. The driving device together with the heating current of the furnace body is controlled by a controlling device such that the sample receptacle engages the furnace body during a drying and decomposing step and thereafter, is raised from the furnace body by the driving device. Thereafter, with raised sample receptacle, the furnace body is heated to atomization temperature until a temperature stabilization is achieved and, finally, the sample receptacle is again moved into contact with the furnace body.
