Teillösung

Thank you very much! I am still kind of confused by the SOPs, though. The unofficial WHO document about vaccines also speaks of "starting material" etc. But maybe the posted references will make it clear. Haven't found any other term than simply "solution" here (unless you're going to term it "product" and describe production stages, something that has little to do with chemistry).

Best wishes

NaOH cannot be deemed an intermediate in such a reaction, if anything it is a reagent

having a look at it now..

Couldn't it simply be the "intermediate"?

"In general, the term 'batch' more often refers to intermediates or final formulated bulks which are in one or a few large containers, while 'lot' usually refers to the final product in the final container."

Teillösung not the final product IMHO. Text from the WHO QSS.

It's a heading in a document showing procedures to follow when preparing batches.

Again, where do you take the partial from? There's nothing partially dissolved etc. The solution itself is also complete, it is simply mixed with another. In addition, there is nothing that is going to be separated - as in case of your fraction. It's the other way around (going to be mixed). Or you say "starting solution".

I believe the references I posted were perfectly clear: You can just say first/second/third solution. It's not my fault Germans have to over-specify things :)

What Björn describes in his discussion entry below, I'd just call "solution part 1a, 2b..., "solution fraction" (of the entire solution) or - only perhaps (!) - "partial solution" (see Nils' answer).

Hope this is not only a "partial solution" of your problem...;-))

I would really appreciate any feedback you can give me. The "hyper-correctness" I mentioned refers to the fact that Germans have a special term for anything and everything (can sometimes drive you almost insane). See:

"In dem erfindungsgemäßen Verfahren geschieht dies, indem die Monomerlösung in zwei Teillösungen (Flüssigkeitsströme 1a und 1b) aufgeteilt wird, wobei die eine Teillösung das Oxidationsmittel und die andere Teillösung das Reduktionsmittel des Redox-Initiators enthält."
http://www.google.st/patents/WO2006120232A1?cl=de

"Diese Lösung besteht aus drei Teillösungen, d.h. einer Aminosäurelösung mit Elektrolyten, einer Kohlenhydratlösung mit Elektrolyten und einer glycerinfreien Fettemulsion, die unmittelbar vor Applikation miteinander vermischt werden."
http://www.google.com/patents/EP0625313A1?cl=de

"die sog. „Aktivierungslösung“ wird aus zwei Teillösungen hergestellt, welche man jede für sich ansetzt und später zusammengibt!"
http://www1.tu-darmstadt.de/fb/ch/cfs/Schnuppertag2005.pdf

At least to me, that just sounds like a normal compound (Teillösung -> Lösung als Teil der späteren Lösung), nothing specialized. That was what my answer was based on. What do you think?

though chemistry would be the better classification IMO too

Is "HERSTELLUNG DER TEILLOSUNG 1M-NATRIUMHYDROXID-LOSUNG" a heading or part of a sentence...?
