Exchange Resin, for Ion Chromatography, IR-120.

Exchange Resin, for Ion Chromatography, IR-120.

Description:

IR-120 is a premium strong acid cation exchange resin designed for high-efficiency ion chromatography (IC) and water purification applications. It is typically supplied in the hydrogen (H⁺) form and composed of a sulfonated polystyrene-divinylbenzene (DVB) copolymer matrix, providing excellent mechanical and chemical stability.

Key Features:

• Type: Strong acid cation exchanger

• Matrix: Sulfonated polystyrene cross-linked with divinylbenzene (DVB)

• Form: Hydrogen (H⁺) form (can also be converted to Na⁺ or other forms)

• Ionic Capacity: ~1.8–2.0 meq/mL (dry basis)

• Particle Size: 16–50 mesh or 20–50 mesh (standard for IC applications)

• Appearance: Amber to dark brown beads

• Thermal Stability: Up to ~120°C in H⁺ form

• Chemical Stability: Resistant to most acids and bases

Common Applications:

• Ion Chromatography (IC):

  • Separation and quantification of cations such as Na⁺, K⁺, Ca²⁺, Mg²⁺

  • Common in environmental, agricultural, and food testing labs

• Water Demineralization / Softening

• Hydrogen cycle operation in mixed-bed or column systems

• Catalysis support for acid-catalyzed reactions in chemical synthesis

• Educational use in analytical chemistry experiments
