Coulometric and volumetric titrations If the water content is too high for coulometric Karl Fischer titration, the 852 Titrando can handle this without any problem. With this instrument you have the possibility of analyzing samples with water contents ranging from only a few micrograms up to 100%. Bromine index As a new feature the 852 Titrando offers the possibility of determining 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. Automatic titration start It can happen very quickly that the sample is injected into the titration cell without first pressing the start button. In this case the water of the sample is conditioned away and the determination has to be repeated. With the 852 Titrando this wont happen to you ever again. The instrument recognizes the addition of sample and starts the determination automatically. In this way you save not only reagents but also sample and, above all, precious time. Dosino and Dosing unit Up to four Dosinos and Dosing units can be attached to the MSB-ports of the Coulometer. In combination with the 852 Titrando these can be used for volumetric Karl Fischer titrations as well as addition of the sample, water standard or auxiliary solutions like solubilizers.
Furthermore the reagent exchange can be automated, which means that the titration cell does not need to be opened and therefore no moisture can enter the cell. Long conditioning times after a reagent exchange can thus be avoided. |
