X-Ray Fluorescence Spectrometry (XRF Analysis)
XRF is an analytical technique used to determine the elemental composition of inorganic based materials. It is typically used for bulk chemical analysis on solids and powders.
X-rays irradiate a sample and the elements present emit a fluorescent X-ray radiation that is characteristic for those elements. Analysing crystals are used to disperse the different energies. A detector is used to measure the intensity of the X-rays and wavelength. Extensive calibration enables quantification of results.
The Benefits of XRF
- Fast turnaround
- Relatively low cost
- Bulk analysis
- Typical detection limit of around 0.01% for most elements
- Quantitative analysis
- Most elements detremined.
- QA/QC control
- Batch conformity testing
- Research and development
- Raw material and intermediary analysis
- Identification of unknown materials
Typical Industries using XRF
- Medical devices
- Cement manufacturers
- Glass and ceramic manufacturers
