Honeywell HYDRANAL-Coulomat AK is a specialized, methanol-free anolyte reagent for coulometric Karl Fischer titration, specifically formulated to measure trace water in ketone-containing samples where methanol would interfere. It's used in diaphragm cells, offering high accuracy by suppressing side reactions, and is part of Honeywell's trusted HYDRANAL portfolio for consistent water content analysis in chemicals, pharmaceuticals, and other materials. Key Features & Description:
- Application: Coulometric Karl Fischer Titration (KF) for water determination.
- Sample Type: Ideal for samples containing ketones (e.g., acetone, MEK) that react with methanol.
- Methanol-Free: Essential for avoiding side reactions with ketones, ensuring accurate results.
- Cell Type: Designed for use with titration cells featuring a diaphragm.
- Function: Acts as the anolyte (positive electrode solution) in the titration cell.
- Appearance: May develop a slight brown tint (trace iodine) with age, which can be removed by exposure to humid air before use.
- Brand: Part of Honeywell's high-quality HYDRANAL line, known for reliability in KF analysis.
How it Works:When performing coulometric KF titration, an electric current generates the titrant (iodine) in situ, and Coulomat AK provides the electrolyte system to facilitate this reaction efficiently in ketone matrices, allowing for precise measurement of very low water levels.
The Honeywell 34820 (often listed as HYDRANAL - Coulomat AK) is a specialized reagent used in laboratory water determination. It is known for its high purity and compatibility with specific titration techniques, specifically designed for coulometric Karl Fischer titration, especially when testing ketone-based samples.
