Cross-linked PS

In the world of chromatography, choosing the right stationary phase or matrix can make all the difference. High-performance polymer materials based on polystyrene/divinylbenzene (PS/DVB) and polymethacrylate are emerging as a powerful alternative with unique advantages:

• Robustness: High mechanical strength for longer column life and reliable performance.
• Wide pH Tolerance: Enables separations across a broader pH range than silica.
• Solvent Compatibility: Excellent compatibility with various organic solvents, acids and bases.
• Tunable Porosity: Precise control over pore size for customized separations.

At Echo Bio we don't just offer PS/DVB chromatographic resin; we provide the tools to precisely tailor your stationary phase to your unique separation challenges. Experience unparalleled control and performance with our extensive customization options:

1. Porosity Perfection:

• Non-porous PS/DVB: Ideal for separating smaller molecules and achieving high-resolution separations.
• Mesoporous PS/DVB: Available with a range of pore sizes from 100Å to 4000Å, allowing you to optimize separations based on the size and shape of your target molecules.

2. Various Cross-linking :

• Low Cross-linking (2-10%): Provides greater flexibility and higher loading capacity, suitable for larger biomolecules and milder separation conditions.
• High Cross-linking (80%): Offers exceptional rigidity and mechanical strength for high-pressure applications and challenging separations.

3. Surface Functionality Finesse:

• Hydrophilic: Ideal for aqueous applications and separations of polar compounds.
• Hydrophobic: Suited for reversed-phase chromatography and separations of non-polar molecules.
• Ion Exchange: Cationic or anionic functional groups for charge-based separations.
• Affinity: Immobilize specific ligands for highly selective capture and purification of target molecules

4. Size Spectrum:

Microspheres: Available in a wide range of sizes, from 2 μm to 100 μm, allowing you to fine-tune resolution, flow rate, and loading capacity.
