XRF Services

Sampling Services use X-ray Fluorescence Spectrometers (XRF Analyzers) to deliver fast, non destructive screening for the presence of metallic elements. XRF results are both qualitative and quantitative.

What is XRF?

XRF (X-Ray Fluorescence) is a well established technique for positively identifying materials. The technique is quick, reliable and non-destructive.

XRF has two main applications:
- Positive Material Identification
- Screening - eg. confirm the levels of heavy metals are within acceptable limits.

During the XRF process X-Rays are directed on to the material that is being tested. X-Rays cause atoms to go into an excited, higher energy state. As the atoms relax to their normal state a characteristic radiation is emitted and it is this information that the XRF analyser uses to identify the elements present.

The XRF analyser compares the ratios of the elements detected to a library of known alloys. XRF provides qualitative and quantitative data.

What is XRF Used For?

XRF analysis is ideal for the identification and screening of metals and alloys.

Positive Material Identification (PMI) – XRF is ideal for distinguishing different metals and alloys.
XRF is a non-destructive test and is ideal for:
- Identifying metal stock eg. Sheet metal, Bars, Tubes etc.,
- Identifying components, comparing type of alloys within a product.

Screening – XRF is ideal for carrying out high speed screening for contamination by heavy metals in consumer goods and toys.
