01

XPS Surface Contamination Survey

Monochromated Al Kα survey plus high-resolution core-level scans of Fe 2p, Cr 2p, Ni 2p, O 1s, and C 1s. Includes quantification of oxide states and trace elements on stainless steel and nickel alloys. Delivered with peak-fit tables and atomic concentration report.

02

Auger Depth Profile – Multilayer Coating

Focused electron beam combined with Ar⁺ sputtering to resolve elemental composition vs. depth for up to 10 layers. Depth resolution ≤2 nm. Includes interface width measurement, diffusion zone analysis, and coating thickness calibration.

03

Passivation Layer Integrity Assessment

Angle-resolved XPS and low-energy ion scattering to determine oxide film stoichiometry, thickness (1–20 nm), and hydroxide/oxide ratio on Al, Ti, Ni-based alloys. Maps Cr enrichment in stainless steels and identifies breakdown precursors.

04

Custom Multi-Technique Surface Package

Combine XPS, AES, and ISS in a single workflow for correlative analysis of oxidation states, elemental depth distribution, and outermost monolayer composition. Ideal for failure analysis and process validation on complex alloy surfaces.
