Auxiliaries for Karl Fischer Titration by Merck: Buffer Solutions, Salicylic Acid, Imidazole, Benzoic Acid and Molecular Sieves for Accurate Water Determination
Reliable water determination in analytical chemistry depends on complete sample dissolution and maintaining optimal pH. Samples containing strong acids or bases may disrupt the Karl Fischer reaction, risking inaccurate results. This page explores essential auxiliaries—including buffers, salicylic acid, imidazole, benzoic acid, and molecular sieves—designed to stabilize reactions for precise analysis.
Benefits of Auxiliaries for Karl Fischer Titration
- Accurate water determination support: Helps achieve accurate water determination results by addressing two critical requirements, complete sample dissolution and maintenance of the correct pH range.
- Stable pH conditions for reliable results: Supports the Karl Fischer reaction by maintaining a pH between 5 and 7, which is important for correct analysis.
- Improved suitability for challenging samples: Provides a practical way to work with samples containing strong acids or strong bases that may otherwise disturb the reaction conditions.
- Consistent analysis under disturbed pH conditions: Helps keep the reaction in the optimum pH range when sample composition pushes the pH out of equilibrium.
- Ready-to-use convenience: Offers ready-to-use solutions that can be added to maintain suitable reaction conditions for accurate Karl Fischer results.
