X-Ray Fluorescence (XRF)

Definition - What does X-Ray Fluorescence (XRF) mean?

X-ray fluorescence (XRF) is an analytical method that makes use of X-rays' interaction with target samples in order to determine elements present along with proportions or the overall elemental composition.

This technique is non-destructive and entirely safe. With this method, fragile or delicate products can be analyzed under average atmospheric pressure with no risk of damage. This form of micro-analysis has paved the way for quick and easy elemental characterization of materials.

Corrosionpedia explains X-Ray Fluorescence (XRF)

As a powerful tool for qualitative and quantitative elemental analysis tool, XRF can be used for archaeological, environmental, biological, industrial and geological analysis.

Compared to other methods, XRF is faster, more cost effective, multi-elemental and non-destructive. It gives a uniform and better detection level throughout a large portion of the table of elements. XRF is used in a broad range of concentrations, ranging from 100% down into a few parts per million.

This technique is widely used by archaeologists, museum curators and conservators to determine vital information about the artifacts under investigation. This can also be utilized to identify corrosion products, which can help in the conservation and care of priceless historical artifacts as well as archaeological collections.

Additionally, XRF can be used to measure film composition, thickness and identification of elemental concentration of elements. It is also applicable in the fields of telecommunications, metal finishing, food refining, cosmetics, semiconductors and more.
