Fusion solution

The principle of melting is to dissolve the sample in a borate salt (also called melting) melted at high temperature. After controlled cooling in a mold, a glass disk is formed ready for XRF analysis. Fusion is mainly used in areas where samples are difficult to mineralize and where conventional techniques become long, expensive, using strong acids such as HF, or leading to incomplete mineralization. This technique allows the complete mineralization of samples such as cements and their raw materials, ores, geological samples, alloys, phosphates or fertilizers, ceramics, catalysts (…). The preparation of glass discs makes it possible to circumvent the many disadvantages of pressed pellets (interference, multiplication of calibrations, risk of breaking the pellet in the XRF, influence of mineralogy and particle size, etc.), to gain precision, to facilitate analyzes by simplifying calibrations because less interference, to respond to analytical rates with multi-station devices (4 or 6) and the ability to automate this step (contact us).
