X-Ray Fluorescence Spectroscopy

Sherlock Holmes meets science. The answer here at the XRF division is always "Elementary, my dear Watson". Discover how the periodic table lights up when samples are exposed to X-rays.


The Thermo Fisher ARL Perform’X can analyse for elements ranging from Fluorine up to Uranium. A carbon crystal is added to improve the detection/sensitivity of carbon. However, this remains qualitative.

The instrument has a 4.2kW power supply system with a Rh target 50 µm window. The goniometer contains four collimators (0.15°, 0.4°, 1° and 2.5° angular admittance), six analysing crystals (AX-06, AX-16C, AX03, Ge111, LiF200 and LiF220) and two detectors (flow proportional and scintillation). Primary beam filters include Al20, Al200, Al500, Al750 and Cu250.


The XRF can analyse major and trace elements using quantitative (OXSAS) and semi-quantitative programs (UniQuant & Qantas). Pressed powder samples are used for trace element and semi-quantitative analyses of smaller samples. Fused beads are used for major element analysis and semi-quantitative analyses of major element samples.

We do analyses for Tertiary Institutions, Industries, Mining Companies, Construction Companies, etc.

Anyone curious enough about bulk sample elemental composition is always welcome!
