XRF Analytical Considerations for Oxidation Fusion Methods The webinar will focus on various applications used to test the quality of a wide range of materials, with an emphasis on sample preparation for obtaining accurate and precise results.
When analyzing powders by XRF, sample inhomogeneities due to segregation, grain size and mineralogical effects can affect intensity and cause errors. Fusion offers the advantage of destroying the matrix and mineralogy, allowing the laboratory to use a single calibration method to analyze a wide range of elements.
Analytical considerations are discussed when setting up the analytical method. Some materials, such as ferroalloys, sulphides, and carbides, require oxidation fusion for accurate analysis. The fusion method serves as a reference for the certification of in-house secondary reference materials for your laboratory.
Advantages of fusion:
Eliminates analytical errors due to grain size and mineralogy Matrix effects are reduced due to dilution Standards can be prepared synthetically Wide oxide calibration can be used to analyze all sample types (oxides, non-oxides including metals, s, carbides, and graphite) Analytical accuracy is improved for a variety of samples, broadening possible applications through fusion A broad oxide fusion method can be set up to analyse all the materials in your laboratory
During the 45-minute complimentary webinar, an XRF Specialist from Rigaku will guide the session, focusing on the accurate analysis of various materials. Rigaku will demonstrate how to develop and set up a fusion method and discuss considerations when fusing different materials, such as ferroalloys, sulphides, and carbides that require oxidation. The webinar will conclude with a Q&A session, providing you with an opportunity to ask any specific questions you may have. |
