Agilent MCX Aqueous SEC Columns
Agilent MCX columns are designed for aqueous SEC analysis of strong polyanions like poly(styrene sulfonate), lignin sulfonate, modified starches, acids, alcohols, and pectins. These GPC columns feature a sulfonated styrene-divinylbenzene copolymer base, that can be used to analyse sulfonated polymers with molar masses ranging from 100 to 5,000,000 Da. Available in two particle sizes and featuring a range of porosities, MCX columns cater to diverse polymer analysis requirements. Additionally, they meet USP L22 classification, exhibit high tolerance to buffer concentrations, pH range from 1 to 13, temperatures up to 80°C, and can withstand organic solvents, including up to 100% methanol or acetonitrile.
- MCX columns are packed with highly porous particles of a sulfonated styrenedivinylbenzene copolymer
- Recommended for aqueous SEC separation of sulfonated polanions
- Meets USP L22 designation
- Compatible with a wide range of aqueous eluents with optimum performance when used with eluents that have a pH in the range 7.0 to 13.0
- Shipped in water with 7.5mM sodium azide to prevent microbial growth
- Choice of particle sizes (5 µm and 10 µm) with a variety of porosities from 100 Å to 10,000,000 Å
- Excellent separation efficiency obtained by narrow particle size distribution and optimised frit technology
- Suitable for use with high buffer concentrations, pH range of 1 to 13, and organic solvents (up to 100% methanol or acetonitrile)
- Columns manufactured under DIN EN ISO 9001 quality standards
- Each column individually tested with a certificate of analysis available
- Guard columns protect and extend the lifetime of analytical columns
