What Is XRF

- Dec 05, 2017 -

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.
