| Popis: |
An energy-dispersive X-ray fluorescence spectrometer has been developed that provides in situ analyses for thirty elements in the 5 to 50 ppm range (dry weight) in sediments at water depths to 100 m. The analyzer consists of a radionuclide excitation source, 109 Cd, and a solid cryogen-cooled Si(Li) detector with a 0.2-mm beryllium window. The spectrometer has been designed to analyze elements in sediment surfaces as well as a function of sediment depth. The spectrometer has been utilized on a minisubmersible and from a surface vessel. This instrument was applied to several environmental studies. The in situ spectrometer is compared with a laboratory X-ray fluorescence spectrometer. |
