Waters Corp Sep-Pak Alumina A 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 50 - 300 µm, 20/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.

Analyte retention can occur via hydrogen bonding, dipole-dipole interactions, or cation-exchange in aqueous samples.
- Designed as a precision chromatographic tool for sample enrichment and purification.
- Contains a polar stationary phase for adsorbing analytes from non-polar solvents.
- Manufactured with high-quality, clean, dry, and reproducible packings.
- Packings offer optimal surface area, pore-size, and particle-size distributions.
- Sealed in a non-contaminating poly-foil pouch to maintain integrity and purity until opened.
- Enables easy sample extraction and preparation and convenient transfer without spillage or evaporation.
