Yes, the EVA KF Titrators can analyze samples that are not soluble in Karl Fischer solvent. The EVA V1 titrator has several applicative approaches to bring the water of an insoluble sample into the KF solution, including elevated temperature (by the use of a thermostatable vessel), internal extraction (by the use of auxiliary solvents), and gas-phase extraction (DO308 oven). However, for challenging samples, the EVA V3 titrator is recommended as it offers additional features such as homogenizers that crush the sample and bring the water into solution, blank methods to adjust the result for water entry during homogenizing, and external extraction, allowing users to extract water from the sample using a solvent and measure aliquots from the resulting solution.
