German term or phrase: nach Volhard

Die Untersuchungsprobe wird mit heissem Wasser extrahiert, und die Proteine werden ausgefällt. Nach Filtration und Ansäuern wird dem Extrakt Silbernitrat-Lösung im Überschuss zugesetzt. Der Überschuss an Silberionen wird nach Volhard mit Kaliumthiocyanat-Lösung zurücktitriert.

Ich habe das gefunden: http://de.wikipedia.org/wiki/Titration_nach_Volhard
Aber ich bin noch nicht überzeugt. Ideen wären sehr geschätzt. Vielen Dank!

YAY! I've added [[Volhard titration]]. Now wikipedia doesn't have what we do!
I just hope to be able to remix it again when I write a general chemistry laboratory booklet...
