    • 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.
    • 用于样品中元素多元素测量的原子发射光谱仪包括:雾化样品并激发用于发射特征谱线的原子的装置;产生由焦平面中的原子发射的光的光谱的分散装置 以及多个半导体光电检测器,其中的每一个都暴露于所述特征谱线之一。 利用多个半导体光电检测器,其暴露于由各个元件的原子发射的线谱的不同强度的不同谱线,以便为每个要测量的元件获得足够大的动态范围。 为了测量每个元件,评估电路被布置为选择一个半导体光电检测器,其中相关联的谱线的强度位于尽可能有利的半导体光电探测器的测量范围的一部分内。

    • A polymer composition, a process for the production of a polymer composition, in particular of an absorbent, are disclosed which substantially consist of a special component A based on renewable polysaccharide raw materials, a special component B consisting of a water-soluble polymer, a matrix material, an ionic and/or covalent cross-linking agent, or an anti-blocking agent, which is obtainable in that the water-swellable polymer is brought together with the polysaccharide polymer, that these are dried and ground then, the other components are added, and mixing up to homogeneity is effected followed by a heat treatment, and that during the addition of the cross-linking agent, after said heat treatment, the same is optionally fixed by the matrix by means of a final heat treatment. Additionally the use of this polymer composition and (animal) hygiene items and chemico-technical products are disclosed which comprise a previously manufactured polymer composition.
