Webinar: XRF methods for loose powder, pressed powder and fusion

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

There are three main sample preparation techniques for the measurements of powders with XRF namely pressed powder, loose powder and fusion. In either case proper sample preparation accessories are needed. This webinar shows you the different methods for preparing powder samples. Each sample preparation requires a specific analytical method to determine the elements in the powders. The differences are shown in the analytical methods.

Comparisons are shown for the differences in the loose powder and pressed powder methods. The fusion method is better than pressed powder since we eliminate the matrix and mineralogical effects shown with pressed powders and the error from grain size is eliminated in fusion and produces a homogenous sample. The pressed powder is the best method for process control and is best for the determination of the light elements that are volatile during the fusion method. The loose powder has some disadvantages since the film used during the analysis absorbs the light elements like F and B.

The best sample preparation method must be chosen depending on the considering elements precision and accuracy required.

During the 45-minute complimentary Webinar you will be hosted by the XRF Specialist from Rigaku and XRF Specialist from FLUXANA. During the Webinar Fluxana and Rigaku will show you how to prepare powder samples and show the differences in the analytical results. 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. Participation in the webinar is of course free of charge.
