At the laboratory level, fluorescence is used for the determination of material characteristics, chemical and elemental analysis. Through the emission of X-rays, the atoms of the tested material are excited and subsequently emit fluorescence, called X-ray fluorescence.<\/p>\n

With the X-ray fluorescence method, the composition of any element can be measured. This method is used in the analysis of metals, building materials, ceramics, and in the field of geochemistry and forensic science.<\/p>\n

HOW X-RAY FLUORESCENCE WORKS<\/h2>\n

As you can read in the \"fluorescence: how it works<\/a>\"For fluorescence to be generated, there must be an absorption of energy and the emitter must be in a higher energy band in the light spectrum than the receiver. X-rays are in the energy spectrum above all the visible colours of the spectrum, so we are going to be in a band even higher than ultraviolet light.<\/p>\n

\"Espectro<\/p>\n

Subsequently, the elements that are irradiated with X-rays will emit a wave (fluorescence), which is characteristic of each of the elements. In this way we will be able to identify the elements contained in the sample (qualitative analysis), and its maximum intensity will give us the amount of the element in the sample (quantitative analysis). With this method, all elements can be measured, from sodium to uranium, and with concentrations from ppm to high concentrations.<\/p>\n

\"Ejemplo<\/p>\n

Applications of X-RAY FLUORESCENCE<\/span><\/h2>\n

As mentioned above, X-ray fluorescence can be applied for elemental composition analysis, and can be used for elements ranging from Beryllium or Sodium to elements such as Uranium. The most typical applications are:<\/p>\n

    \n
  • Steel irons, low and medium<\/li>\n
  • Lead alloys<\/li>\n
  • Geological samples<\/li>\n
  • Stainless steels.<\/li>\n
  • Majority per bead of sands, aluminosilicates, limes and limestones (UNE 80-211-94) (0.6 g minimum sample).<\/li>\n<\/ul>\n

    X-ray fluorescence is also known by its acronym XRF, and has the following competitive advantages:<\/p>\n

      \n
    • The X-ray fluorescence technique is environmentally friendly and non-destructive.<\/li>\n
    • With this technique you can measure all elements, from Beryllium to Uranium, both qualitatively and quantitatively.<\/li>\n
    • Both measurements and sample preparation are carried out quickly, making it a very accurate measurement technique.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
