MATi 11 (MATi = Metrohm Automated Titration) is a completely configured system for water content determination in solid or liquid samples using automated volumetric Karl Fischer titration. It contains a Polytron PT 1300 D for the homogenization of the samples. Up to 53 samples are analyzed directly in 120 mL titration beakers. The samples are weighed in the titration beaker and sealed with aluminum foil and a foil holder so that they neither lose nor absorb water.
