Bill, I have the FDC beside me. On pages 57 & 117 the mention of Schneour is very ambiguous because you don't say who he is and his name only ever crops up in relation to you & Rodinal. Gerald Koch, who's opinions I respect is the source of the second quote which is here on APUG.
If Elie Schneour has definitive data on Rodinal where is it ? I could have done spectrographic analysis on Rodinal & other developers lf but in fact it's quite difficult to determine what's in a compouded developer. I had two Varian AA Spectrometers in the lab I ran, and access to other instruments as we worked closely with 2 or 3 other labs specialising in different testing methods, however as Ron (PE) could confirm some elements or salts are difficult to detect and measure. Getting a full analysis done is extremely expensive.
I'd request you don't turn threads like this on APUG into the ill tempered and bitter threads that you've taken part in so many times before on various forums.
I don't doubt that the formula published by Agfa themselves in Andresen's book is the closest formula to Rodinal that Agfa has ever published. (Which is the formula in the FDC). Other people may have been closer to the mark.
