    Description / Table of Contents: Zusammenfassung Einige Verbesserungen der maßanalytischen Bestimmungsmethode für Fluor in organischen Substanzen wurden beschrieben, nämlich: a) Einführung eines Zusatzreagens zur Erzielung einer vollständigen Überführung in Fluorwasserstoff bei der elektrischen Verbrennung im verschlossenen Kolben; b) Verwendung einer Pufferlösung von Glycin und Perchlorat zur Gewährleistung einer stöchiometrischen Titration; c) Anpassung eines automatischen Titriergerätes für photometrische Titrationen zwecks besserer Wahrnehmung des Endpunktes. Außerdem wird empfohlen, zur Berechnung des Fluorgehaltes eine lineare Gleichung zu verwenden.
    Notes: Summary Some improvements of the titrimetrio method for determining fluorine in organic compounds are described. The modifications involve:(a) introduction of a combustion aid for the electrically heated flask combustion to insure complete conversion of fluorine to hydrogen fluoride, (b) employment of a glycine-perchlorate buffer to maintain a consistent stoichiometric titration, and (c) adaptation of an automatic titrimeter for photometric titration to simplify the detection of the end point. It is also suggested that a linear equation be derived from the calibration data in order to calculate the fluorine content.
