A good overall introduction to XPS http://www.youtube.com/watch?v=kK5OBNJwnws and a quick look at what XPS spectrometers look like is given in this short video from the Center on Materials and Devices for Information Technology Research (CMDITR) Seattle.
Good example of the steps involved in a simple XPS quantitative analysis is presented in this video from the Materials Research Facilities Network (MRFN.org) in the US.
Note however that XPS is sensitive to all elements in the periodic table *except* hydrogen, although the presence of hydrogen can often be detected indirectly.
An example of hands-on XPS training is given in this MRFN video http://www.youtube.com/watch?v=pTLJ2zW_z6c
Note that although at one point it is said that "adhesive pumps down, its not a problem" this is not always the case. It certainly can be a problem, depending on the type and quantity of adhesive. Talk to NEXUS before using any adhesives on samples you intend to send or bring to us. Its not easy to see much of the detail of XPS operation from this video, but it gives an idea of what is covered in some introductory "hands-on" training. Don't try to follow everything though - its difficult to describe things fully in a video without being able to look through a viewport easily.
NEXUS has a site licence for the CasaXPS software package, and makes it available to NEXUS users. Shortly this will be possible via remote web-access.
At NEXUS' suggestion Neal Fairley of CasaXPS has very kindly produced a set of introductory videos to assist new users.
We would welcome other software vendors to do the same if they find it useful; we would be very happy to link to such videos.
