Dolomite Microfluidics specializes in the production of high-performance nano- and microparticles which are precision-engineered for advanced functionality and encapsulation. These materials have unique properties determined by their size, shape and architecture which enable them to be used as specialized research tools within biomedicine, diagnostic imaging and industrial catalysis. They depend on technologies which can accurately characterize these 5 nm – 500 µm particles, ensuring that their size and morphology both lie within tightly-controlled limits. Their go-to technique to manage these requirements was transmission electron microscopy (TEM), a reliable yet expensive, time-consuming and therefore low-throughput process which became a limiting factor in their production efficiency. Pavel Abdulkin, Particle Works’ Co-Founder and the Head of Chemistry at Dolomite Microfluidics, said: “By using the Zetasizer Ultra to test our samples we were able to significantly reduce the amount of TEM that we perform, which has enabled us to streamline both our R&D process and our Quality Control, and significantly reduce our analytical costs. Our sample throughput has increased dramatically – we are now looking at around one month per development cycle, as opposed to the 12 months this originally required.”

Major investments are often made in state-of-the-art XRF equipment without knowing that the whole analytical chain, including the weighing step in sample preparation prior to fusion, is of crucial importance to get precise and accurate analytical results and consequently obtain estimated financial pay-offs. In fact, precision and accuracy of results enable the manufacturer to decrease the level of uncertainty associated with the concentrations of its products, and therefore avoid huge losses in revenue. The weighing step in sample preparation by fusion for XRF analysis is all about knowing the exact weights of the sample and the flux (sample-to-flux ratio). Consequently, the weighing method, the tolerance accepted as well as the analytical method to obtain this ratio will affect the quality of analytical results given by the spectrometer. There are many ways to weigh the sample and the flux prior to fusion: • Manual weighing (most widespread technique) • Automated weighing (with Claisse® LeDoser™ or LeDoser-12™ for example) • Weighing the sample and the flux directly in the platinum (Pt) crucible • Weighing the sample or the flux in another container, reusable or not, before transferring it into the Pt crucible • Pre-weighed flux vials • Weight correction on the XRF instrument (exact weight needs to be known) All these weighing methods affect the precision of the sample-to-flux ratio and consequently impact the final analytical results. In this application note, the effect of the different weighing methods on the precision (RSD) of the obtained XRF results are compared.

Mining companies can lose millions of dollars if a slight bias is found in their whole ore analysis process. Their profitability then depends on the quality of their elemental analysis. This study shows that it is possible to use NaT flux coupled with an automatic fusion instrument to build a calibration strategy for XRF analysis that meets the ISO 9516-1 requirement for iron ore analysis. A calibration strategy based on CRMs prepared with NaT as flux is comparable to lithium-based flux for iron ore analysis. The developed method allows fast and repeatable analysis of iron ores in accordance with the currently accepted international norm. This method is a nice alternative to lithium-based flux used for sample preparation by fusion.
