If simple evaporation is not an option, e.g., for the analysis of crude oil, tar, turpentine, resins, or terpenes, then you can use the KF Evaporator.
This instrument applies the principle of azeotropic distillation, meaning that a solvent is added to the sample and the mixture is heated. The water evaporates with this solvent, and the mixture is transferred to the titration cell and analyzed.
As an added benefit, the titration cell and the electrode are not contaminated and secondary reactions are excluded, since only the water reaches the titration cell.
