When your business considers an XRF purchase, there are many details to consider and many questions that you may have. What is XRF? What does XRF do? What elements does it analyze? Is XRF accurate? Is it fast?
Whilst handheld XRF can be used by non-experts, with pre-programmed settings allowing positive materials identification, the detection of impurities in production materials or the screening of food for toxic heavy metals (and more), you may still be curious about what is happening behind the scenes in handheld XRF guns.
If you and your coworkers are asking yourselves these questions and want to know more, you will find some helpful answers below.
XRF is an acronym for X-ray fluorescence, a process whereby electrons are displaced from their atomic orbital positions, releasing a burst of energy characteristic of a specific element. This release of energy is then registered by the detector in the XRF instrument, which in turn categorizes the energies by element. Here is a detailed breakdown of the process:
The entire fluorescence process occurs in small factions of a second. A measurement using this process and a modern handheld XRF gun can be made in a matter of seconds. The actual time required for a measurement will depend on the nature of the sample and the levels of interest. High percentage levels will take a few seconds while part-per-million levels will take a few minutes.
