XRF Analytical Considerations for the Oxidation Fusion Methods - Part 2

Presenter: Carmen Kaiser-Bruegmann

XRF is used as the major analytical technique in various application fields and can be used to test the quality of various materials.

The Webinar will focus on various applications used to test the quality of a wide range of materials. The most important is the sample preparation of the various types of materials to obtain accurate and precise results.

During the analysis of powders by XRF, sample inhomogeneity due to segregation, grain size, and mineralogical effects influence the intensity and cause errors. The fusion method is beneficial in that the matrix and mineralogy are destroyed. This method means a laboratory only requires one calibration method for the analysis of a wide range of elements.

The analytical considerations are discussed when setting up the analytical method.

Some materials like ferro alloys , sulphide and carbides require a oxidation fusion.

The fusion method is a reference method that can be used to certify inhouse secondary reference materials for your laboratory. Advantages of fusion:

• Analysis error due to grain size and mineralogy removed
• Matrix effect is reduced due to dilution
• Standards can be prepared synthetically
• Wide oxide calibration to analyse all sample types (oxides, non-oxides including metals, sulphides, carbides, and graphite)
• Analytical accuracy is improved for a variety of samples broadening possible applications by fusion
• Wide oxide fusion method can be setup to analyse all materials in your laboratory

During the 45-minute Webinar you will be hosted by an XRF Specialist from Rigaku on the accurate analysis of the various materials. During the Webinar Rigaku will show you how to develop and setup a fusion method and what to consider when fusing different materials like ferro alloys, sulfide and carbide materials that require oxidation. The webinar concludes with a Q&A session.
