I am interested to better understand the mathematics supporting and used in performing a zero concentration extrapolation on small-angle and wide-angle x-ray/neutron scattering. Can anyone recommend a good source?
I am trying to download Glatter & Kratky's book using the link below but just get a blank page (maybe the server for the page is down?). Can you reccommend another link?

For the next person looking for the text by Glatter and Kratky, I just came across the link below post on the SAXIER forum (http://www.saxier.org/forum/viewtopic.php?t=178): http://web.archive.org/web/20110824105537/http://physchem.kfunigraz.ac.at/sm/Service/Glatter_Kratky_SAXS_1982.zip
Pages 225-227 has a great explanation. The quick answer to my question is on page 225, "Linear extrapolation of the intensities often works well when the concentration effect is weak and the concentrations are low." The mathematics of performing a linear extrapolation (including correctly handling the error propagation) can be found in many places on-line; I found this one helpful: http://www.che.udel.edu/pdf/FittingData.pdf.

Steven, thanks for the link, but it didn't work for me... I'll Google it!
For an in-print (and expensive) book get hold of "Neutrons, X-rays and light scattering methods applied to soft condensed matter", ed. Linder and Zemb, 2002. This is a beautiful collection of review articles on all you wanted to know
