Description

Dowex G26 Hydrogen Form is a high-purity, strongly acidic cation exchange resin supplied in its hydrogen (H+) ionic form. This product is essential for critical separation and purification processes where consistent ion exchange capacity and chemical stability are paramount. It is primarily utilized by industries requiring ultrapure water, metal recovery, and catalysis. The material is identified by CAS No. 210235-42-0.

Application

• Ultrapure Water Production: Key polishing resin in mixed-bed and condensate polishing units for power generation, semiconductor, and pharmaceutical water systems.
• Catalysis & Organic Synthesis: Serves as a solid acid catalyst for esterification, alkylation, and hydrolysis reactions, offering easy separation and reusability.
• Metal Separation & Recovery: Selective removal and concentration of valuable or toxic metal cations (e.g., Cu, Ni, Co) from industrial process streams and mining leachates.
• Sugar & Sweetener Processing: Decolorization, demineralization, and inversion of sugar syrups to improve yield and product quality.
• Pharmaceutical Purification: Purification of antibiotics, amino acids, and other active pharmaceutical ingredients (APIs) through ion exchange chromatography.
• Analytical Chemistry: Used in ion chromatography columns and sample preparation for the separation and analysis of cationic species.
• Chemical Dealkalization: Softening and dealkalization of boiler feed water and process water to prevent scaling.

Quality Control

Our Dowex G26 Hydrogen Form is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets specifications for exchange capacity, moisture content, particle size distribution, and chemical stability. Certificates of Analysis (COA) documenting these parameters are available upon request. We adhere to industry best practices suitable for applications in water treatment, food processing, and pharmaceutical industries.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the original container sealed to prevent moisture uptake and contamination. Do not allow the resin to freeze or be exposed to extreme heat.
