X-rays form part of the electromagnetic spectrum. They are on the high energy side of ultraviolet, and are expressed in terms of their energy in kilo electron volts (keV), or wavelength in nanometers (nm). X-ray fluorescence (XRF) can typically analyse elements from sodium to uranium, in concentrations ranging from parts per million to high percents, in solids, liquids, and powders.
The elements and concentrations that XRF analysers can determine depend on the material being tested, and the instrument used.
