The analysis of solid surfaces, oriented to scientific and research work, is fundamental in the study of their mechanical, physical and chemical properties. Photoelectronic spectroscopic techniques of surface analysis are based on the study of the energy of the electrons emitted by the solid when it is irradiated with X-ray photons (X-ray photoelectronic spectroscopy – XPS -) or ultraviolet ones (ultraviolet photoelectronic spectroscopy – UPS -). These techniques allow the identification of the elements and provide detailed information on the state of the chemical bonds and the concentration of the surface atoms.

The Photoelectronic Spectroscopy Service provides analytical support to the research staff of the Catalysis and Petrochemical Institute and other CSIC centres, as well as to universities, research centres and private companies or organisations that request it.

Analysis request
To request the analysis, the XPS and/or UPS Request must be completed and delivered with the samples to the Technical Director of the Service.
In case pressure and temperature pre-treatment and subsequent analysis is desired, please fill out only the HPC+Analysis Request form.

Operation Guide
Before submitting the Application, please read carefully the Guide to the Operation of the Photoelectronic Spectroscopy Service

Maximum delivery time of results per Application Form

XPS Analysis 4 months
Ion pickling analysis + XPS 6 months
HPC + XPS analysis 6 months
UPS Analysis 4 months

Current deadlines for requests for analysis after 12/11/2019.
Deadlines are in calendar days.
The deadlines are conditioned to having deposited the samples to be analyzed at the Photoelectronic Spectroscopy Service.
In order not to increase waiting times for other users, for those principal investigators who submit more than 1 Application Form every 15 days for any of the techniques offered by the Service, the delivery time for results will be doubled.
When special analysis conditions are requested, as reflected in the Annexes to the Application Forms, the delivery time for the results will depend on the demand for the Service at any given time, with a maximum period of 6 months.
These periods may be modified due to vacation periods, leaves of absence, lack of availability of personnel, etc.

Current rates for analysis requests after 17/01/2020.
In the case of hourly pricing, only the full hours (rounded up) of pre-processing carried out or spectrum analysis delivered to the user will be counted.
Special rates will be applied with those entities with which there are agreements or arrangements.
Where applicable, VAT will be applied.
These rates do not include the interpretation of results.
Depth Profile results will be delivered by pickling time. In the case that it is desired by unit of depth and the Photoelectronic Spectroscopy Service does not have the data for the conditions of analysis that the applicant wishes, the applicant must provide the reference material, as well as will be economically responsible for the depth profile of the same.

Other information

In order to help XPS users, you can download a class on XPS given by Miguel Antonio Peña Jiménez in the context of different courses on characterization of inorganic materials. The presentation describes the basic fundamentals of the technique and gives the basis for the manipulation and interpretation of spectra.

Click here to download the Oberon MS Excel 97 spreadsheet, which allows you to determine all the XPS and Auger lines that a given sample can present, from its elemental atomic composition. When you open the file, you must choose the option “Enable Macros”. This is a trial version, so user suggestions are welcome.
