XRF analysis is a non-destructive technique capable of semi-quantitative analysis, alloy ID and RoHS screening.

How XRF Testing is Performed

X-rays are emitted from the miniature X-ray tube in the analyzer and strike the sample, knocking electrons out of the innermost orbitals.  Electrons from outer orbitals move into the vacated spots to stabilize the newly created ion, and in the process emit energy (a secondary X-ray photon) that is characteristic to each specific element.  This phenomenon is called fluorescence.

XRF Testing - Quantitative Analysis of Materials

Wavelength-Dispersive X-Ray Fluorescence Spectroscopy (WD-XRF) offers the compositional analysis of various metals. The method requires a solid sample able to cover a 29mm diameter opening; however, smaller samples can be accommodated. Note that some light elements (such as boron, beryllium, etc.) cannot be detected via this method.

XRF Testing- Featured Benefits


XRF Testing can be performed quickly, delivering an accurate quantitative analysis on a wide variety of materials


XRF Testing is performed with no adverse effects to the material sample


The analyzer can be used in the hand-held mode or in the integrated test stand. The unit is portable which allows for on-site testing.


XRF Analysis is less expensive than ICP Testing. 

XRF Testing FAQ's

What is XRF Testing?

XRF analysis is a non-destructive technique capable of semi-quantitative analysis, alloy ID and RoHS screening.

What materials can be XRF tested?

XRF testing can be performed on metals such as iron, aluminum, magnesium, titanium, copper, nickel, chromium, bromium, lead, cadmium, and mercury. XRF testing can also be approved on non-metals, such as polymers, liquids, and soils.

The instrument aperture (or window) is about 5 mm in diameter (about the size of a pencil eraser).  Samples as small as half this size can be individually analyzed easily, and even smaller samples can be analyzed as long as enough multiple parts are provided.  Powder samples can be analyzed by placing enough powder to thoroughly cover the aperture in a clear plastic bag.  Samples should be at least 5 mm thick for polymers and 1 mm thick for metal alloys to prevent the X-rays from completely penetrating through the sample.
