I have obtained and read the publication by Elving et al in Analytical Chemistry, Vol. 28 #7, pages 1179-1180 (1956). In that publication they list formulas for mixing the Citric acid and Na2HPO4 solutions to prepare the various pH buffers. They are basically using the identical ratios of these...

This is no help. I am asking specifically for help in understanding the methods used by Elving et al to obtain the IS values shown in their table.
