TITRATION

Karl Fischer titration is the specific standard method for the determination of water content and gives accurate and precise results within just a few minutes. Titration is a quantitative chemical analysis. It is used to determine an unknown concentration of a known substance in a sample. The basic principle of the titration is a solution (titrant or standard solution) is added to sample to be analyzed. The titrant contains a known concentration of a chemical which reacts with the substance to be determined. The titrant is added by means of an automatic burette. Due to the chemical reaction taking place in the sample to be analyzed, the characteristics of the sample changes. This change of the characteristics is detected by a sensor. A sensor shows a significant change in the signal measured as soon as all the substance contained in the sample has reacted with the titrant added.
