The “XPS Spectral Library of Common Materials” is a truly unique, “self-consistent” collection of more than 8,500 digitized XPS spectra that were obtained by measuring commonplace materials (e.g.  alloys, glasses, metals, minerals, oxides, polymers, etc.) under well controlled experimental conditions. A table of contents that summarizes the contents of this library is provided just at the right of this description.

This library of spectra was measured over a 10 year time period by a single scientist who used two well characterized XPS systems equipped with an Al monochromatic X-ray source.  Under these conditions the collection is considered to be a “self-consistent” collection of spectra which maximizes the reliability of the data, the numbers and information derived from them, and also the comparisons made with spectra that are produced by the user. 

The “XPS Spectral Library of Common Materials” of 8,500 spectra is stored in over 1,700 multi-spectra data-files which are systematically organized as a modular system of 50 directories with names that are easily recognized by analysts, engineers, scientists, and teachers.

The spectral data contained within this library are designed to assist engineers, scientists, analysts, theoreticians, and teachers who use XPS on an everyday basis under practical working conditions. These spectra will help XPS users to analyze industrial problems, gather reference data, perform basic research, test theories, and teach others.  The main purpose of this collection is to provide reliable spectra that can be used in a practical manner on a daily basis by many different XPS users with different needs and responsibilities.

The spectra in this library are designed to be practical, reference spectra for everyday use and comparisons and were obtained under practical working conditions.  Even though research grade spectra were not the target of the methodology used, there are, in fact, many hundreds of research grade spectra in this library.

The “self-consistent” methodology used to produce this library of spectra has greatly minimized the random and systematic errors that cause various troubles in other collections of BE numbers or spectra that were produced by gathering BEs or spectra produced by many different groups who used many different instruments, many different charge compensation methods,  and many different energy scale calibration styles.

By design, the directories, filenames, and samples have names and descriptions that directly identify the basic content or the purpose of each directory or file.  Most of these names are very familiar to XPS users, analysts, engineers, scientists, and teachers.  Numerical filenames, which add an unnecessary level of complication, were not used.  All systems or libraries produced by XPS International LLC are designed to be practical, systematically organized, easy to use, and easy to understand. 

The “XPS Spectral Library of Common Materials” currently occupies about 100 MB of memory in binary form or about 150 MB in ASCII form, and is supplied on CD-ROMs.

With the purchase of the “XPS Spectral Library #1 of Common Materials”, the user will receive a free copy of the advanced spectral data processing software, “Spectral Data Processor v4.3” and a set of 27 computer-based training movies each 5-10 min. long to teach how to operate SDP.
