Embodiment Construction
[0016] The technical solution of the present invention will be further explained below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, a graphite crystal pre-diffraction X-ray fluorescence analysis device consists of an X-ray excitation system 1, a sample box 5, a graphite crystal diffraction optical path 8, a Si-PIN detector multi-channel system 9, a computer data acquisition and processing system, etc. 10 composition. Among them, the X-ray tube excitation system 1 adopts a 100-250W low-power high-voltage generator, and the operating voltage and current are 30-50kV and 1-5mA respectively. It is matched with a low-power Ag target or Rh target X-ray tube. The detector of the detector multi-channel system 9 adopts a Si-PIN detector, and a graphite crystal pre-diffraction device 8 is added between the detector and the sample 5 to eliminate the influence of the radioactivity of the sample 6 itself. The sample box 5 is injection molded from pol...
