Multi element - atomic absorption spectrometer as well as measuring process with use of such an atomic absorption spectrometer

摘要

Multi element - atomic absorption spectrometer (1) has at least two lines to be examined at least one element emitting lamps (20, 21; 30, 31); a the sample to be examined in the atomized state heating atomiser (5), at least one optical spectral element (9) with a this upstream entrance slit (41, 42) detector elements (55), as well as devices (4; 43, 47) for directing radiation coming from the lamps by the atomiser, by means of the entrance slit and said spectral element to the detector elements, as well as measuring devices (10, 11; 56), characterized in that replaceable optical reflection means (27, 38, 39) which can be provided, optionally in such a manner into the beam path of the lamps can be inserted, that the radiation of a, two or more lamps at the same time, on a common optical axis with the use according to the number of lights of the whole, in each case of a half or a part of the solid angle of each lamp can be conducted by the atomiser that said spectral element for generating a two-dimensional a spectral dispersion - echelle grating (46) as well as a dispersion prism (44)..
