Description

Poly(Styrene-Co-Divinylbenzene), 2 Percent Cross-Linked, 100-200 Mesh is a synthetic, macroporous copolymer resin widely used as a robust chromatographic support and catalyst carrier. Its controlled 2% cross-linking with divinylbenzene provides an optimal balance of mechanical stability and accessible surface area for high-performance separations. This product is essential for industries requiring reliable solid-phase extraction, ion exchange, and size-exclusion chromatography processes.

Application

• Chromatographic Stationary Phase: Primarily used as a packing material for High-Performance Liquid Chromatography (HPLC) and Size Exclusion Chromatography (SEC) for polymer and biomolecule analysis.
• Solid-Phase Extraction (SPE): Serves as a sorbent medium for the purification and concentration of analytes from complex matrices in environmental, pharmaceutical, and food testing.
• Ion Exchange Resin: The functionalized form of this base resin is used for water demineralization, metal recovery, and catalysis in chemical synthesis.
• Polymer Support & Catalyst Carrier: Acts as an inert, high-surface-area support for immobilizing catalysts and reagents in combinatorial chemistry and industrial catalytic processes.
• Gel Permeation Chromatography (GPC): Employed for determining the molecular weight distribution of synthetic polymers and natural macromolecules.
• Adsorbent for Organic Compounds: Used in the removal or recovery of organic substances from aqueous and gaseous streams.

Quality Control

Our Poly(Styrene-Co-Divinylbenzene) resins are manufactured under strict quality protocols to ensure batch-to-batch consistency for critical separation applications. Each lot is tested for key physical and chemical parameters, including particle size distribution, cross-linking density, porosity, and chemical stability. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture uptake, which can affect performance.
