Key Features:
1. Advanced Dual-Modification Technology
Sulfonic Acid Modification: The PS/DVB surface is first modified with sulfonic acid groups (-SO3H), creating a stable hydrophilic layer.
Metal Ion Chelation: The phase is further chelated with Calcium (Ca²⁺), Lead (Pb²⁺), Sodium (Na⁺), or Potassium (K⁺). This allows users to select the optimal column based on specific separation requirements for different sugar types (e.g., mono- vs. disaccharides).
2. Superior Matrix Structure
Low Cross-Linking PS/DVB: The support material features a low cross-linking degree (5%, 8%, and 10%), optimized for the separation of small organic molecules.
Spherical Geometry: The uniform spherical particle shape ensures excellent packing density and column bed stability.
3. High Separation Efficiency
Tight Particle Distribution: Available in 5 µm and 10 µm particle sizes with uniform distribution, minimizing eddy diffusion and maximizing theoretical plate numbers for sharp peak shapes.
