Special X-ray Photoelectron Spectroscopy (XPS) Testing Analytical Service

Special X-ray Photoelectron Spectroscopy (XPS) Testing Analytical Service

SKU: SPXPS001

  • $ 39885



Overview

Capable of micro-area XPS, depth profiling, Auger spectroscopy, and valence band spectroscopy.

Instrument Models: PHI-5000 Versaprobe III, Thermo Scientific ESCALAB 250Xi, Thermo Scientific Nexsa, etc.

Testing Notes

  1. XPS Capabilities: Standard full-spectrum and narrow-spectrum tests, Auger spectroscopy, valence band spectroscopy, depth profiling, mapping, and angle-resolved analysis.

  2. Element Range: XPS can detect elements from Li to Cm; H and He cannot be analyzed.

  3. Data Analysis: XPS data analysis can provide elemental valence states and semi-quantitative data. Elements with an atomic percentage below 5% may not produce a significant signal.

  4. Default Source: Unless specified otherwise, the default source is monochromatic Al Kα (Mono AlKa) with an energy of 1486.6 eV.

  5. Spectral Overlaps: Using Al Kα X-rays may result in overlapping peaks. When overlaps occur, direct quantification is unreliable. Common solutions include:

    • a. Peak fitting during data analysis to re-quantify,
    • b. Testing peaks of other orbitals (please specify the required orbital; the strongest peak is used by default),
    • c. Switching to another target, such as an Mg target, if overlaps with certain Auger peaks occur.

    Common Overlapping Peaks include:

    • Li1s & Co3p; B1s & P2s; C1s & Ru3d5/2, Ru3d3/2; C1s & K2p; O1s & NaKLL; O1s & Pd3p3/2; O1s & Sb3d5/2; N1s & Mo3p3/2; N1s & GaLMM; Al2p & Pt4f5/2; Si2p & Pt5s; Mo3d5/2 & S2s; Ta4f & O2s; Co2p & FeLMM; Mn2p & NiLMM; W4f & Zr4p; Al2p & Cu3p.
  6. Data Provision: XPS test data is provided as raw data without any correction. Since correction methods vary by material, a video guide on correction procedures can be provided upon request.

Sample Requirement

  • Bulk and Thin Film Samples: Bulk/thin film sample dimensions should be larger than 5 × 5 × 3 mm and smaller than 60 mm in diameter and 8 mm in height.
  • Special Liquid Samples (Ionic Liquids): Can be directly injected for testing. Most liquids are dried on the substrate surface before testing, with the same size requirement of larger than 5 × 5 × 3 mm.

* Note: Data analysis service is not included in the list prices.

Highlights: High Quality Data, Competitive Pricing, Technical Support by Scientists.

Analytical Service Minimum order requirement: $250 per order. A $200 handling fee will be applied if order is below $250.
