What are the Benefits of Fusion Sample Preparation?

Sample preparation involves the treatment of a sample before analysis. In XRF applications, the better the sample's preparation, the more precise the results become. Different methods for sample preparation offer distinct advantages.

This article, in particular, will focus on the utilization of a fusion machine for preparing XRF samples.

Fusion Sample Preparation

For XRF analysis, fused bead creation via fusion provides a nearly perfect, homogeneous sample representation. This method is ideal for solid samples.

Gas and electric fusion machines can be used to perform this sample preparation. Fused beads are produced by combining a flux with finely powdered samples and heating the mixture to temperatures ranging from 1000 °C to 1200 °C in a platinum crucible.

This process dissolves the sample into the flux, and it is then cast into a mold. This results in the creation of a fused bead devoid of mineral structures. Fusion machine-based sample preparation diminishes matrix effects, enhancing analysis accuracy. It also permits the combination of multiple samples in the same calibration process.

XRF Scientific's fusion machines utilize borate fusion, a process that dissolves oxidized samples in molten flux.

Common samples prepared through borate fusion include ceramics, rocks, ores, and cement. Sub-oxidized samples can also undergo borate fusion after an oxidation step. Lithium tetraborate and lithium metaborate are typical fluxes used in borate fusion.

Gas or Electric Fusion Machines

XRF Scientific offers both gas and electric fusion machines for XRF sample preparation, each with unique advantages. Both electric and gas fusion machines ensure long-term reliability, reducing the need for maintenance and machine downtime. Additionally, reactions within the machines are observable.

Gas machines provide the highest level of automatic throughput, facilitating efficient sample preparation with minimal sample contamination. Electric automatic machines offer zero sample contamination and high automatic throughput. Manual electric machines provide straightforward operation and the highest level of manual throughput.
