R\u00f6ntgenfluoreszenz (XRF)<\/h1><\/div>

R\u00f6ntgenfluoreszenz (XRF) ist eine Methode zur chemischen Analyse (Elementaranalzse) von Proben. Bei dieser Technik wird ein energiereicher Elektronenstrahl (wie bei EDX) auf die Probe gerichtet. Der Elektronenstrahl regt Elektronen der inneren Elektronenschalen der Probe an wodurch L\u00f6cher entstehen die von Elektronen der \u00e4u\u00dferen Schalen besetzt werden. Bei dieser Bewegung werden zus\u00e4tzlich R\u00f6ntgenphotonen emittiert. Das Energieniveau dieser Photonen ist elementspezifisch wodurch die chemische Zusammensetzung bestimmt werden kann.<\/p>\n

XRF Analysatoren gibt es als station\u00e4re Laborinstrumente aber auch als mobile Ger\u00e4te.<\/p>\n

Anwendungsgebiete sind:<\/p>\n

    \n
  • Detektion von gef\u00e4hrlichen Inhaltsstoffen z.B. in Kunststoffen, Farben, Elektronik\n
      \n
    • RoHS<\/li>\n
    • REACH<\/li>\n
    • SVHC<\/li>\n<\/ul>\n<\/li>\n
    • Detektion von Schwermetallen in Erdproben<\/li>\n
    • Zerst\u00f6rungsfreie Materialbestimmung<\/li>\n
    • Positive Materialidentifikation (PMI) z.B. Sortieren von Metallen<\/li>\n
    • Geochemische Analysen im Bergbau<\/li>\n
    • Analyse von Edelmetallen<\/li>\n<\/ul>\n<\/div>
