The design and construction of a new two-crystal x-ray spectrometer are described together with the observed Mg Kα, Al Kα, Si Kα, S Kα, and Cu Kα1 spectra. The spectrometer is designed for x-ray fluorescence analysis and has a wide scanning range (2° to 146° 2θ) under vacuum. Excellent reproducibility of 0.4 s in arc is attainable, which makes possible the observation of chemical shifts in x-ray spectra. Magnesium Kα was found to be influenced by the coordination number, proving that the spectrometer is useful for chemical state analysis.
