Thermo Scientific™ AmberChrom™ Dowex® 50WX8 (H) 200-400 mesh

Thermo Scientific™ Dowex® 50WX8 (H) is a strongly acidic cation exchange resin in the hydrogen form, composed of a crosslinked styrene-divinylbenzene gel matrix with 8% cross-linkage. Supplied in 200–400 mesh bead form, this resin is widely used in ion exchange chromatography, low-pressure liquid chromatography (LPLC), and other cation exchange separation techniques. It is particularly effective in applications requiring fine particle size and high resolution, including water deionization, biochemical separations, and sample purification.

Key Features

• Strong Acid Cation Exchange Resin – Sulfonic acid groups for efficient proton exchange
• Hydrogen Form (H⁺) – Ready-to-use for deionization and protonation reactions
• High Cross-Linking (8%) – Provides mechanical and chemical stability
• Fine Mesh Size (200–400 mesh) – Ideal for high-resolution separations and small-volume applications
• High Exchange Capacity – ~1.1 meq/mL (wetted bed volume)
• Moisture Content – 50–58%, with ~55% loss on drying at 110 °C
• Form – Uniform, free-flowing beads for reproducible column packing
