Description

Amberlite XAD 8 is a macroreticular, cross-linked acrylic ester polymer resin widely used as a non-ionic adsorbent. Its primary value lies in its exceptional ability to separate and purify organic compounds from aqueous solutions via hydrophobic interactions. This makes it a critical component for process engineers and researchers in the pharmaceutical, environmental, and fine chemical industries who require efficient and scalable purification solutions.

Application

• Pharmaceutical Purification: Isolation and purification of antibiotics, steroids, and other active pharmaceutical ingredients (APIs) from fermentation broths or reaction mixtures.
• Environmental Analysis & Remediation: Pre-concentration and removal of trace organic pollutants, pesticides, and phenolic compounds from water and wastewater streams.
• Natural Product Extraction: Recovery of valuable compounds such as flavonoids, alkaloids, and pigments from plant extracts and biological fluids.
• Decolorization Processes: Removal of colored impurities and organic contaminants in the sugar, food, and chemical manufacturing industries.
• Catalyst & Reagent Support: Serving as a solid support matrix for immobilizing catalysts or reagents in synthetic chemistry applications.
• Analytical Sample Preparation: Used in solid-phase extraction (SPE) cartridges for the clean-up and concentration of analytes prior to HPLC or GC analysis.

Quality Control

Our Amberlite XAD 8 is manufactured under a strict quality management system. Each lot undergoes rigorous testing for critical parameters including particle size distribution, surface area, pore volume, and moisture content to ensure consistent adsorption performance and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The resin should be kept moist or regenerated prior to storage to prevent drying and cracking.
