Description

Amberlite(R) IRA-400 (Cl) is a strongly basic anion exchange resin supplied in the chloride form. This high-capacity, gel-type resin is essential for critical separation, purification, and catalysis processes across numerous industries. It is particularly valued for its robust performance in demineralization, deionization, and the removal of anions from process streams. Key sectors that rely on this product include water treatment, pharmaceuticals, chemical synthesis, and food & beverage production.

Application

• Water Purification & Demineralization: Core component in mixed-bed and separate-bed deionizers for producing high-purity water for power generation, laboratories, and electronics manufacturing.
• Pharmaceutical Purification: Used in the purification of antibiotics, vitamins, and other active pharmaceutical ingredients (APIs), as well as in the preparation of pyrogen-free water.
• Chemical Process Catalysis & Separation: Serves as a catalyst or reagent support in organic synthesis and for the removal of acidic impurities or specific anions from chemical process streams.
• Food & Beverage Processing: Employed in decolorization, deacidification, and the removal of off-taste components in sugar syrups, fruit juices, and other edible products.
• Hydrometallurgy & Metal Recovery: Facilitates the recovery and separation of precious metals like gold and platinum, or the removal of contaminant anions from mining and metal plating effluents.
• Condensate Polishing: Used in power plants to remove ionic contaminants from steam condensate, protecting boilers and turbines from corrosion and scaling.

Quality Control

Every batch of Amberlite(R) IRA-400 (Cl) is manufactured and tested under a strict quality management system. Specifications for key parameters such as total exchange capacity, moisture content, particle size distribution, and chloride form uniformity are rigorously verified. Certificates of Analysis (COA) documenting these results are provided to ensure traceability and compliance with your procurement standards.

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). Avoid freezing and prolonged exposure to temperatures above 40°C. Keep the original container sealed to prevent moisture absorption and contamination. Keep away from strong oxidizing agents.
