Product Name – Buffer for total hardness (ammonia/ammonium chloride/EDTA 2S Mg), pH 10 AVS TITRINORM® buffers at 20 °C
Quantity/Pack Size – 500 ml
Form – Liquid
Grade – Analytical
Application – EDTA titration for water hardness testing
Product Overview
This pH 10 buffer solution is specifically formulated for EDTA titration methods to determine total water hardness with exceptional accuracy. The ammonia/ammonium chloride base provides stable pH control at 20°C, ensuring reliable endpoint detection during complexometric titrations. As an AVS TITRINORM® certified buffer, it meets international analytical standards for water quality testing. The solution contains magnesium-EDTA complex (EDTA 2S Mg) that serves as an ideal indicator system for calcium and magnesium determination. Its ready-to-use liquid form eliminates preparation steps while maintaining consistent performance across multiple tests. The analytical grade formulation guarantees minimal interference from contaminants, making it suitable for both routine laboratory analysis and research applications requiring high precision. The buffer’s stability at room temperature ensures long shelf life without degradation of its titrimetric properties. Each batch undergoes rigorous quality control to verify its buffering capacity and compatibility with standard EDTA titrants.
FAQs
