XRF Light Elements Analysis

Light element analysis via handheld x-ray fluorescence used to be challenging. X-ray fluorescence depends on the ability of the detector to detect emitted fluorescent energies that are unique to each element (see XRF for Alloy Grade Analyzers). The lighter the element, or the lower its atomic number, the weaker its fluorescent energies and the shorter the distance that the energy can travel.

The light elements in the context of x-ray fluorescence are Magnesium (Mg), Aluminum (Al), Silicon (Si), Phosphorus (P), Sulfur (S), and Chlorine (Cl).

Light elements have such weak fluorescent energies that it is difficult for them to travel the distance between the sample surface and the detector during XRF analysis, as they lose their energy within a very short distance. This makes detecting light elements with XRF challenging.

A common solution to the XRF detection problem for light elements has been to create a vacuum or to use helium to purge the path between the sample surface and the detector. However, state-of-the-art detector technology has made these "fixes" largely unnecessary for alloy analysis. The Bruker S1 TITAN uses a highly sensitive silicon drift detector (SDD) that means even weak XRF signals can be accurately measured. The detection ability of its sensor makes the S1 TITAN ideal for light element analysis. 

If light element analysis and quantification are important for your alloy grade identification and sorting needs, be sure to choose the best technology available in portable XRF: the innovative SDD found in the Bruker S1 TITAN – our XRF elemental analyzer that covers all of your needs!

The Bruker S1 TITAN not only provides the grade identification of most alloys in seconds along with complete quantitative alloy elemental composition,it also provides light element analysis without the need of a helium or vacuum purge. The detection of light elements with XRF is easily possible and takes only seconds.

The S1 TITAN uses cutting-edge technology not only in its detector, but also in the form of SharpBeamTM technology. These beam geometry and detector innovations make the S1 TITAN an industry leader in terms of both speed and detection limits. The S1 TITAN provides near laboratory-quality elemental composition determination, even for the light elements, and is well suited to a wide range of applications.
