XRF sample preparation requires absolute precision to ensure that accurate results are obtained with a high degree of repeatability, for example: flux measurements must be carried out with exactitude to ensure the best possible sample purity and the consistency of test parameters.

Flux measurements are necessary but time-consuming tasks which are often performed manually during XRF sample preparation processes. However, dedicated flux measurement equipment has been developed to reduce the tediousness and improve the accuracy of this stage of the procedure through automated measurement and dosing of fusion flux powders.

XRF Scientific manufactures and supplies two intuitive flux weighing mechanisms proven to advance precision and traceability of fusion flux compound measure...

Developers and manufacturers of scientific equipment have been exploiting the unique mechanical characteristics of platinum (Pt) for over 200 years, because of its high melting point, ductility, malleability, and low reactivity. As a result, platinum crucibles have become fundamentally important components for various chemical research applications in laboratory environments.

The applications of platinum crucibles range from XRF sample preparation to ash testing, and each sector requires equipment with highly specialized mechanical properties and differing volumetric dimensions. Pure platinum and its alloys are applied to meet these varying requirements, with a choice of materials available from XRF Scientific, including:

• Pure platinum crucibles, with a melting point...

Lithium metaborate (LiBO₂) is a chemical compound used in borate fusion for x-ray fluorescence (XRF) analysis, and in fusion flux mixtures for other sample preparation methods.

It is available from XRF Scientific as lithium metaborate 100%, which is available in both granular and beaded physical structures, both of which have a high reactivity with acidic samples and a melting point of 845°C, accounting for its low volatility. It, therefore, has a high suitability to wet chemistry applications.

We also supply fusion flux chemicals comprised of lithium metaborate and lithium tetraborate (Li₂B₄O₇), as well as various oxidizing additives, for a range of XRF sample preparation applications.
