Description

BeschreibungDescription

Die Erfindung betrifft eine Vorrichtung zum gravimetrischen Titrieren gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for gravimetric titration according to the preamble of claim 1.

Die gravimetrische Titration hatte nur noch historische Bedeutung, da sie von der Handhabung bisher zu aufwendig und zu kompliziert war. Sie war völlig von der volumetrischen Titration verdrängt worden.Gravimetric titration was only of historical importance, as it was too laborious and complicated to handle. It had been completely replaced by volumetric titration.

Die volumetrische Titration zeigt jedoch erhebliche Nachteile, bedingt durch die thermische Ausdehnung der Titrationslösung und durch mögliche Blasenbildung in den Bestandteilen des Dosiersystems für den Titrator.However, volumetric titration has significant disadvantages due to the thermal expansion of the titration solution and the possible formation of bubbles in the components of the dosing system for the titrator.

Die gravimetrische Titration dagegen ist durch die Verwendung von molalen Lösungen (mol/kg) temperaturunabängig und durch Blasenbildung nicht beeinträchtigt.Gravimetric titration, on the other hand, is independent of temperature due to the use of molal solutions (mol/kg) and is not affected by bubble formation.

Dementsprechend liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung für die gravimetrische Titration bereitzustellen, die einfachst zu bedienen ist, und dabei mit minimalem Zeitaufwand hochgenaue Meßergebnisse liefert.Accordingly, the invention is based on the object of providing a device for gravimetric titration which is extremely easy to operate and which delivers highly accurate measurement results with minimal expenditure of time.

Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a device having the features of claim 1.
