Accurate surfacial element analysis, including valance state anlysis
XPS (X-ray Photoelectron Spectroscopy)
Thermo Escalab 250Xi
Al Ka (1486.6 eV)
• Qualitative composition analysis
Confirm the existence of certainelement (sensitivity 0.1 at%), but XPS is less accurate for quantitative analysis;
• Valance state analysis
Analyze the chemical environment and valance states of the elements on the sample surface.
• XPS Depth Profile
Using Ar ions to sputter and etch the sample and perform XPS analyses after each etching cycle.
• <5 nm for metal, inorganic materials;
• <10 nm for plastic, polymers, organic materials.
• 7 Working Days
