This poster describes a method for automated and precise dosing of liquid samples into the Karl Fischer titration cell using Metrohm Dosino liquid handling technology. First, the titer was automatically determined with ultrapure water. The same dosing procedure proved valuable for the automated water determination in highly viscous water-glycol fluids and low-boiling organic solvents such as n-pentane. Lastly, the method copes with the labor-intensive and human error-prone suitability test stipulated in chapter 2.5.12 in the European Pharmacopoeia.
