Coulometric Titration - Fast and More Efficient
Sep 14 2021
New Aquastar® coulometric reagent for Karl Fischer water determination.
Many samples for Karl Fischer titration dissolve easily in methanol – the alcohol often used in coulometric reagents. However, some samples need the addition of co-solvent or buffer to dissolve or react properly. The new Aquastar® anolyte reagent for cells without diaphragm can be used for a wide variety of samples, especially those that need a solubilizer or buffer to achieve accurate and precise titration results. Low water content in the range of 10ppm to 10,000ppm can be determined fast, precisely and reproducibly. Oils, fats, ointments, strong acids and bases can be measured with the addition of solubilizer or buffers and solid samples, crude oils or motor oils with the Karl Fischer oven method or an external water release.
