What Kind of Tubes Are in A XRF?
X-ray fluorescence spectroscopy (XRF) commonly used X-ray tube with the type of element of rhodium (Rh), silver (Ag), chromium (Cr), molybdenum (Mo), tungsten (W) and so on.
The choice of tube, with the material to be analyzed relevant. In a XRF, rhodium electrode, is the most common models, because rhodium tube, X-ray emitted by the X-ray tube and the continuous X-rays for excitation atomic number 11 (sodium) to an atomic number 30 (Zn) elements. In addition, the tungsten tube is relatively common XRF.
However, in two different targets XRF, have their limitations, the need to use the user to select:
Rhodium tube XRF characteristic lines characteristic lines overlap with cadmium, so testing cadmium, the need for special filters.
Tungsten tube XRF characteristic lines with lead, mercury characteristic spectral overlap, but the emission intensity tungsten target X-ray tube is large, easy to penetrate.
