Elemental analysis is a crucial process in various industries, and the standard method for this analysis is X-ray fluorescence (XRF).
What is the Standard for Elemental Analysis? 7 Key Points to Know
1. XRF: The Gold Standard
XRF has become the "gold standard" for elemental composition analysis in many industries.
2. Non-Destructive Analysis
XRF can identify and quantify the elements present in a bulk material without causing any damage.
3. Sample Preparation
A small sample volume is extracted from the uppermost surface layers of the material or a fragment is taken and homogenized as a fine powder.
4. Benchtop XRF Spectrometer
This device is used to measure the component parts of the sample and develop relative data for the bulk material.
5. Comparison with Other Techniques
Compared to optical emission spectrometry (OES) and laser-induced breakdown spectrometry (LIBS), XRF offers more analytical capabilities and does not leave visible marks on workpieces.
6. Pressed Pellets for Better Results
Pressed pellets provide better analytical results than loose powders because they create a more homogeneous representation of the sample.
7. Importance of Particle Size
The sample should be ground to a particle size of <75µm, with <50µm being ideal for optimal results.
