Simultaneous X-ray fluorescent spectrometer

A spectrometer for the simultaneous measurement of a plurality of spectral lines from a measurement sample (2) having a plurality of wavelength selectors (5a, 6a, 7; 5b, 6b, 7) each selectively supplying light of a particular wavelength to a detector (9), each wavelength selector having a different wavelength is characterized in that at least two different wavelength selectors (5a, 6a, 7; 5b, 6b, 7) can supply the same detector (9) with light from the sample (2) and that the detector (9) is energy dispersive and one has sufficiently high resolving power to separate the detected light of the different wavelengths from the at least two different wavelength selectors by energy.Thus, on the one hand the high resolution of known wavelength dispersions arrangements can be achieved at relatively short measurement times due to simultaneous measurements of different wavelength ranges, on the other hand, the equipment cost, especially the number of detectors and associated measuring electronics significantly reduced, without driving a considerably higher equipment costs in the mechanical field have to.
