01 · Questions
What this test can help examine
- Surface elements and relative content
- Chemical states and valence analysis
- Surface comparison before/after etching or between specimens
02 · Specimens
Information to prepare
- Solid powder, bulk or film specimens
- Surfaces should be protected from contamination
- Vacuum compatibility and size require confirmation
03 · Method
A route matched to the research question
Survey and high-resolution spectra are acquired as needed; ion etching is evaluated for depth information, and fitting and interpretation scope is agreed in advance.
04 · Deliverables
What may be included
- Survey and high-resolution spectra when scoped
- Elemental composition and peak information
- Acquisition and processing conditions
05 · FAQ
Frequently asked questions
What should be confirmed before XPS testing?
Provide the material type, specimen condition, question to be answered and any existing data. An engineer will confirm preparation, test conditions and deliverables.
How are turnaround time and specimen quantity determined?
Turnaround time and specimen quantity depend on specimen condition, test scope and analysis requirements, and are confirmed during technical review.
