Aqualine coulometric range: for low water content at ppm level
Fisher Chemical Aqualine coulometric reagents are ideal for use in coulometric Karl Fischer titrations for detecting low concentrations of water. Our Aqualine anolyte and catholyte solutions have been re-formulated to offer better performance. The improved formulation increases both the speed and accuracy of titration when determining water content at microgram level.
