How to Interpret XRF Peaks?

X-ray Fluorescence (XRF) spectra look simple, but most people interpret XRF peaks incorrectly.
This video shows how to correctly read XRF peaks and avoid the most common mistakes in research and lab analysis.

Interpreting XRF spectra is a core skill in materials science, analytical chemistry, geology, and engineering, yet it is often misunderstood by students and early-stage researchers. In this video, I explain how to correctly interpret XRF peaks using clear, step-by-step logic that you can directly apply in your research papers and lab work.

The video starts with qualitative XRF analysis, explaining how peak positions (energy values) correspond to specific elements through characteristic X-ray lines such as Kα, Kβ, and L lines. You will learn how to recognize true elemental peaks and how to avoid misidentifying overlaps or artifacts.

I then discuss quantitative XRF analysis, where peak height and peak area relate to elemental concentration. The explanation covers why raw peak intensity alone is not enough, and how matrix effects, absorption, and secondary fluorescence influence the final results. Calibration methods and fundamental parameter (FP) concepts are discussed at a conceptual level so that you understand what the software is doing behind the scenes.

This explanation is designed to help you:

Correctly read XRF spectra in research papers
Avoid common peak misinterpretation errors
Understand the difference between qualitative and quantitative XRF analysis
Improve the quality of figures and discussion in journal manuscripts

This video is especially useful for graduate students, researchers, and professionals working with EDXRF, WDXRF, SEM-EDS comparisons, thin films, geochemistry samples, and general elemental analysis.
