XRF Analytical Considerations for Fusion Methods - Part 1

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.

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

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

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 60-minute complimentary Webinar you will be hosted by the 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. The webinar concludes with a Q&A session — your chance to put any specific questions you have.

At the end of the webinar, we provide participants with a download package that contains all the information.
