Thermometric titrator for universal titration applications, especially when no proper potentiometric sensor is available or when potentiometric titration is limited due to contamination of the sensor, e.g., sodium determination, Acid number / Base number. Approved by ASTM D8045 for Acid number in crude oil and petroleum products; Robust technique Ti-Touch: compact potentiometric titrator The 916 Ti-Touch is a potentiometric titrator for routine applications. Designed as an easy-to-use and compact system, it is equipped with a variety of features to make your work more comfortable: color touch screen, shortcuts for favorite methods, a second port for an additional titration stand and buret, and many more.
22/03/2007В В· Best Answer: Endpoint titration uses an indicator. The "endpoint" is usually the inflection point where a the change in pH is great such as going from acid to base. Potentiometric titration uses an automatic titrator or pH meter and points are plotted all along the way so you can see the inflection or Potentiometric titration is a technique similar to direct titration of a redox reaction. It is a useful means of characterizing an acid. No indicator is used; instead the potential is measured across the analyte, typically an electrolyte solution.
06/09/2012 · The first consideration in choosing a titrator is to define the type of titration that is required. This may include acid/base, Karl Fischer (KF), potentiometric, redox, gas phase, complexometric, or precipitation titration. This article focuses on potentiometric and Karl … Ti-Touch: compact potentiometric titrator The 916 Ti-Touch is a potentiometric titrator for routine applications. Designed as an easy-to-use and compact system, it is equipped with a variety of features to make your work more comfortable: color touch screen, shortcuts for favorite methods, a second port for an additional titration stand and buret, and many more.
Determination of anionic and cationic surfactants by potentiometric two-phase titration. Compared to the classical Epton titration, potentiometrically indicated two-phase titrations using organic-solvent-resistant Surfactrodes can be easily automated and require no toxic and environmentally hazardous chloroform. CONDUCTOMETRIC AND POTENTIOMETRIC TITRATION Gda titrations, the electrical conductance or resistance of the solution being titrated; and amperometric titrations, the electric current passing during the course of the titration. In the titrations just mentioned the end point is indicated by a marked change in the electrical quantity that is being measured. 5 CONDUCTOMETRIC TITRATION In this
