Malvern Panalytical C-MBHMW-3078 Aqueous Cationic Column CLM1033

Aqueous cationic GPC/SEC column intended for size-exclusion chromatography of cationic polymers and other high–molecular-weight samples. The column is a mixed-bed, high–molecular-weight stationary phase used to separate polymers by hydrodynamic size in aqueous or compatible organic mobile phases, and is suitable for strongly cationic samples such as chitosan and other water- or organic-soluble cationic polymers. Primary use cases are high–molecular-weight polymer characterization and molecular-weight distribution analysis in research and QC laboratories.

Key Features:

• Column type: Mixed Bed High MW cationic (C-MBHMW-3078, CLM1033)
• Exclusion limit: >10,000,000 Da (polystyrene equivalent)
• Maximum operating pressure: 1500 PSI
• Dimensions: 7.8 mm × 30 cm (300 mm × 7.8 mm)
• Compatible mobile phases: water and a range of organic solvents including THF, acetonitrile, methanol, DMF and DMSO; compatible with 5% acetic acid

Advantages:

• Optimized for separation and characterization of very high–molecular-weight polymers due to a >10M Da exclusion limit
• Mixed-bed high-MW packing provides broad molecular-weight coverage and improved linearity across large size ranges
• Compatibility with aqueous and multiple organic solvents enables analysis of both water-soluble and organic-soluble cationic polymers
• Designed for strongly cationic samples (for example chitosan), supporting reliable analysis of charged polymer systems
