X-Ray Fluorescence (XRF) Laboratory Home > X-Ray Fluorescence (XRF) Laboratory
X-Ray Fluorescence (XRF) technique is a major nuclear analytical technique widely used throughout the world for multi elemental analysis, the identification of basic chemical elements that a material or object is made of. The technique is considered to be a non-destructive method as opposed to other chemical tests that needs the specimen in test to be disintegrated for the purpose. Therefore, it finds advantages for both industrial and R & D activities where the sample should be preserved for future use.
The XRF laboratory of the Life Science Division having understood the above potential of this technique provides analytical tests for local industries, export and import items and academic research purposes that require the identification of elements in a sample. Both qualitative measures where the identification of individual elements simultaneously and quantitative measures for quantifying the percentage or parts per million (ppm) of the sample can be performed.
The laboratory performs mainly three tests,
- Energy dispersive XRF or EDXRF.
- Total internal reflection XRF or TXRF.
- Portable XRF for in-situ tests and non-destructive tests in laboratory for large items.
Testing services can be carried for following sample matrixes for commercial and R&D purposes,
- Soil samples.
- Vegetation samples.
- Food items.
- Minerals and rocks, gems and gold/silver items of suspicious composition.
- Raw metals and metal made items for composition analysis.
- Industrial items both imported or locally manufactured, for composition analysis and authentication.
- Analysis of industrial settings such as water turbines, tubes, ducts, furnaces, metal structures for in-situ analysis for elemental composition analysis and corrosion study.
- Archaeological items such as metal artifact, statues, replicas for composition analysis and authentication of originality.
- Suitable items directed for composition analysis for regulatory or legal purposes.
Comprehensive tests results and reports both qualitative and quantitative elemental analysis are issued directly for customers or designated regulatory bodies for further decision making or regulatory steps respectively.
