How to Read Auger Peaks in XPS (KLL, LMM, MNN, NOO Series)

Описание: Struggling to identify Auger peaks in your XPS spectra? This video shows the simplest way to recognize KLL, LMM, MNN, and NOO series without guesswork.
Perfect for researchers, students, and anyone working with surface chemistry or materials characterization.

Understanding Auger peaks is essential for accurate XPS interpretation. In this video, we break down how Auger transitions occur, why Auger features appear as broad humps at higher binding energies, and how to differentiate them from photoelectron peaks, satellite peaks, shake-up lines, and instrumental artifacts.

You’ll also learn how Auger electron kinetic energy is calculated, why Auger peak positions remain independent of the X-ray source, and how to identify common series such as KLL, LMM, MNN and NOO.

If you’re new to XPS or want a clean, step-by-step method for spotting Auger peaks, this tutorial will help you analyze spectra more confidently. It includes visual cues, examples of peak locations, and practical strategies used in surface science, materials analysis, corrosion studies, catalysts, and thin-film research.

I regularly upload videos on XPS, SEM, TEM, EDX, AFM, materials characterization, and scientific data interpretation. Subscribe if you want clear explanations, hands-on tutorials, and content designed for researchers around the world.
