By irradiating the sample surface with X-rays and exciting photoelectrons from surface atoms, it can accurately detect the kinetic energy and binding energy of photoelectrons, realizing qualitative and semi-quantitative analysis of surface elements, judgment of element chemical valence states, attribution of functional groups, relative content of surface elements and component analysis of thin film\/coating interfaces. XPS detection only targets the ultra-thin area of 2-10 nm on the sample surface with extremely high surface sensitivity, which can accurately characterize micro changes such as surface modification, oxidation, doping, adsorption and corrosion of materials, making up for the shortcomings of conventional bulk detection technologies. This testing service is equipped with the high-end photoelectron spectrometer Thermo Fisher Scientific Escalab 250Xi (USA) with high signal-to-noise ratio and excellent energy resolution. It is suitable for various samples such as powder, solid blocks and thin films. Widely applied in new materials, semiconductors, catalysis, polymers, anti-corrosion coatings, biomedicine and other fields, it provides accurate and authoritative detection data to meet professional needs such as academic paper publication, scientific research conclusion, product performance demonstration and formula mechanism analysis. Technical Parameter English Parameters: Excitation source: Monochromatic Al Kα X-ray with photon energy of 1486.6eV, featuring high light source stability and extremely low baseline noise Energy resolution: Better than 0.45eV (Ag 3d5), which can accurately distinguish subtle chemical shifts and adapt to high-precision valence state peak fitting Analysis depth: Ultra-thin surface layer analysis of 2–10 nm on the sample surface with extreme surface sensitivity, only characterizing surface composition information Detectable element range: All elements except H and He are detectable, supporting elemental qualitative, semi-quantitative, valence state analysis and functional group fitting Imaging spatial resolution: Minimum analysis spot diameter of 20μm, supporting micro-area fixed-point analysis and accurate characterization of local regions Vacuum system: Ultra-high vacuum analysis chamber eliminates air adsorption pollution and ensures authentic and reliable test data Test functions: Supports full spectrum scanning, high-resolution narrow spectrum scanning, element peak fitting and atomic percentage quantitative calculation Product Features High-end imported flagship equipment with authoritative data: Adopting Thermo Fisher Escalab 250Xi, the top-level X-ray photoelectron spectrometer from the USA, which is mainstream high-end equipment in universities and research institutes. It has industry-leading resolution, stability and signal-to-noise ratio, and the test data is widely applicable to SCI papers, national projects, patents and product quality inspection reports. Exclusive surface analysis capability to fill the blind area of bulk testing: Different from bulk detection methods such as XRD and EDS, XPS focuses on the surface analysis within 10nm of materials, accurately capturing trace surface changes such as surface oxidation, modification, doping, adsorption and corrosion, serving as a core tool for material surface mechanism research. Accurate element valence state analysis with comprehensive functions: It can not only perform qualitative and quantitative elemental analysis, but also accurately determine elemental chemical valence states, chemical bond types and functional group attribution, completing peak fitting, atomic content calculation and surface component comparison to meet the needs of refined scientific research analysis. Transparent stepwise charging with high cost performance: The basic package includes 5 conventional elements, with additional charges for extra elements and unified surcharge rules for special quantum dot samples. The charging standard is clear and transparent without hidden consumption, adapting to testing needs of different dimensions. Standardized and highly compatible samples: Suitable for various solid samples such as powder, solid blocks and thin films; pre-consultation service is provided for solution and liquid dispersion systems to avoid sample preparation failure risks and ensure test success rate. Standardized timeliness and comprehensive services: Unified 5-7 working days testing cycle with standardized processes and traceable progress. Complete original spectra, quantitative data, peak fitting data and professional analysis conclusions are provided, which can be directly used for academic and industrial achievement output. Application Fields Catalytic Material Field: Analysis of surface element valence state, determination of active sites, research on element doping modification mechanism and surface adsorption\/desorption behavior of catalysts, supporting catalytic efficiency optimization and mechanism demonstration.
