How are XRF Samples Prepared? 4 Essential Methods Explained

X-ray Fluorescence (XRF) analysis is a powerful tool for determining the chemical composition of materials.

However, the accuracy of XRF results largely depends on how well the samples are prepared.

Here are the four most common ways to prepare samples for XRF analysis.

How are XRF Samples Prepared? 4 Essential Methods Explained

1. No Preparation (Powder Sample)

This method involves using the sample in its raw powder form without any additional preparation.

It is the simplest method but may not always yield the highest quality results due to potential inhomogeneities in the sample.

2. Pressed Pellets

In this method, the powdered sample is placed in a die and compressed using a hydraulic press at high pressure.

This process compacts the sample into a pellet shape, ensuring a more uniform distribution of elements and improving the quality of the analysis.

The preparation involves grinding the sample to a fine powder to ensure homogeneity and proper compaction.

3. Fused Beads

This method is more complex and involves melting the sample with a flux (often a borate mixture) at high temperatures in a platinum crucible.

The molten mixture is then poured into a mold to form a glassy bead.

This technique is particularly useful for highly resistant or inhomogeneous materials, providing a very homogeneous sample for analysis.

The smaller particle size of the initial sample material aids in the fusion process, ensuring a more uniform bead.

4. Additional Pre-Preparation Steps

Before these primary preparation methods, additional steps might be necessary depending on the raw sample's particle size and material type.

These steps typically involve reducing the particle size using methods like grinding or crushing, which help in achieving better homogeneity and compaction in pressed pellets and fused beads.
