HYDRANAL Coulomat A 500ml Honeywell

Honeywell HYDRANAL Coulomat A is a specific, high-quality anolyte reagent used for coulometric Karl Fischer titration to precisely measure trace water in samples, especially effective in cells with diaphragms, known for its reliability, stability, and part of a broader line of KF reagents offering accuracy for water content analysis in various samples like oils and non-polar substances, featuring methanol/chloroform base for optimal performance. Key Features & Use:

• Application: Coulometric Karl Fischer (KF) Titration for determining trace water content.
• Type: Anolyte solution for the anodic compartment in KF titration cells.
• Composition: Contains iodide, an imidazole buffer, and sulfur dioxide in a suitable solvent, often methanol-chloroform based.
• Cell Compatibility: Preferred for use in KF cells that have a diaphragm (separating anode/cathode) for highest accuracy, but also suitable for cells without diaphragms.
• Benefits: High accuracy for trace water, stable titration conditions, long shelf life, and consistent quality.
• Product Line: Part of Honeywell's comprehensive HYDRANAL brand, a leader in KF reagents. 

In Simple Terms:
Think of it as a specialized chemical "detector" for water. When used in a Karl Fischer titrator, Coulomat A provides the necessary chemicals to react with and quantify minute amounts of water in a sample, ensuring precise results for laboratory analysis.
