Enhancing Your XRF Sample Preparation


In addition to our high-purity Spectromelt® fusion fluxes, we offer a number of additives that can greatly enhance and simplify your XRF sample preparation.

Using fusion additives from MilliporeSigma, you benefit in a number of ways. Non-wetting additives like lithium bromide and potassium iodide, for example, act as releasing agents that help to prevent the borate glasses from sticking to the platinum ware. This makes it easier to remove the sample after fusion and protects your equipment. When your sample contains certain substances that might react with your XRF mold, such as metals or sulfides, oxidizers like lithium nitrate or sodium nitrate make sure that the sample is fully oxidized before flux melting or during fusion in order to avoid damage to your expensive platinum ware. Heavy absorbers, e.g. lanthanum oxide, minimize matrix effects and increase spectrometer selectivity.
