Description

Ambersorb(R) 348F is a high-performance, polymeric adsorbent resin designed for the selective removal of organic contaminants. This product is critical for processes requiring reliable purification and protection of sensitive systems from trace-level impurities. It is essential for industries focused on product quality, process efficiency, and environmental compliance, such as water treatment, chemical manufacturing, and electronics.

Application

• Industrial Water Purification: Removal of trace organic compounds, color bodies, and off-tastes from process and wastewater streams.
• Chemical Process Stream Polishing: Final-stage purification of chemical intermediates and solvents to achieve ultra-high purity grades.
• Electronics Grade Chemical Production: Purification of high-purity acids, solvents, and photoresist components for semiconductor and display manufacturing.
• Food & Beverage Processing: Decolorization and deodorization of sweeteners, organic acids, and edible oils.
• Pharmaceutical Intermediate Purification: Scavenging of impurities and catalysts from reaction mixtures in API synthesis.
• Groundwater Remediation: Adsorption of volatile organic compounds (VOCs) and halogenated solvents in environmental cleanup applications.
• Gas Stream Purification: Removal of moisture and organic vapors from compressed air, natural gas, and other industrial gases.

Quality Control

Our Ambersorb(R) 348F is manufactured under a rigorous quality management system. Each lot is tested to ensure consistent performance characteristics such as surface area, pore volume, and particle size distribution. A Certificate of Analysis (COA) documenting key physical and chemical properties is provided with every shipment to guarantee it meets your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture uptake, which can affect performance.
