ABSTRACT:
An essentially iodine-free and pyridine-free single component reagent for volumetric water analysis using the Karl Fischer reaction, a process for making the reagent, and the use of the reagent to determine the water content of a sample. The reagent contains triiodide ions as an oxidizing agent, a buffer such as an amine, a reducing agent such as SO.sub.2, and a solvent. The presence of iodine, if any, is in an amount less than 1% of the amount of the triiodide ions.
