Titrando Detects Water In Liquids, Solids Or Gases

Metrohm has introduced the 851 Titrando titrator for low-level water detection in liquid, solid or gaseous samples. The 851 Titrando offers the possibility to determine the Bromine index coulometrically. The conventional titration cell, as well as the generator electrode with diaphragm, can also be used for this application. Only the anolyte and the catholyte need to be changed.

The instrument recognises the addition of a sample and starts the determination automatically. Up to four dosinos and dosing units can be attached to the MSB ports of the coulometer. In combination with the 851 Titrando, these can be used for the addition of sample, water-standard or auxiliary solutions, such as solubilisers. The reagent exchange can be automated, which means that the titration cell does not need to be opened and, subsequently, no humidity can enter the cell. Long conditioning times after a reagent exchange can thus be avoided.
