Description

Ambersep 900, Oh Form Ion-Exchange Resin is a high-performance, strongly basic anion exchange resin supplied in the hydroxide (OH) form. This product is engineered for superior ion exchange capacity and chemical stability, making it a critical component for advanced purification and separation processes. It is essential for industries requiring the removal of anions, such as chlorides, sulfates, and nitrates, from process streams and final products. Key sectors that rely on this technology include ultrapure water production, pharmaceuticals, power generation, and specialty chemical manufacturing.

Application

• Ultrapure Water (UPW) Production: Final polishing and removal of trace anions in semiconductor, microelectronics, and pharmaceutical water systems.
• Condensate Polishing: Removal of ionic impurities from boiler feedwater and condensate return in thermal and nuclear power plants.
• Chemical Processing: Catalysis, purification of process streams, and recovery of valuable anions in specialty chemical synthesis.
• Pharmaceutical Purification: Deionization and purification steps in active pharmaceutical ingredient (API) manufacturing and formulation.
• Food & Beverage Processing: Water softening, dealkalization, and demineralization for ingredient water and final product quality control.
• Laboratory & Analytical Use: Preparation of high-purity deionized water for analytical reagents and laboratory applications.
• Hydrometallurgy: Recovery and separation of specific anionic species from leach solutions in metal refining.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). The resin is moisture-sensitive (hygroscopic) and should be kept in its original, unopened packaging until use to prevent contamination and uptake of atmospheric carbon dioxide, which can reduce exchange capacity. Keep away from strong acids and oxidizing agents.
