SPE Disks and Cartridges
Waters Corp Vac Cartridge, Alumina A 500 mg, 3 cc, 50 to 300 μm
Waters Sep-Pak Alumina A Vac cartridges are ideal for normal-phase separations and radioactive compound isolation. They feature a highly active, acidic alumina sorbent that provides an extremely polar surface for analyte retention. These cartridges also offer enhanced stability under high pH conditions and can function as low-capacity ion exchangers.
- Highly active grade of alumina with acidic surface chemistry.
- Aluminum oxide surface provides an extremely polar surface for analyte retention.
- Acts as a Lewis acid for diverse applications.
- More stable than unfunctionalized silica under high pH conditions.
- Functions as a low-capacity ion exchanger in aqueous media.
- Unaffected by high-energy radioactivity, suitable for radioactive compound isolation.
- Syringe-barrel design for use with vacuum manifolds and automated SPE instruments.
Waters Corp WATERS CORPORATION Oasis MCX Cartridge, 35 cc, 6 g Sorbent, 60 μm
Oasis MCX cartridges are designed for solid-phase extraction, featuring a mixed-mode cation exchange sorbent for bases. They are built upon a unique water-wettable Oasis HLB Copolymer, providing both reversed-phase and ion exchange modes of retention for enhanced performance.
- Functions as a mixed-mode cation exchange sorbent for bases.
- Constructed with water-wettable Oasis HLB Copolymer.
- Offers both reversed-phase and ion exchange retention capabilities.
- Ensures greater cleanup selectivity and sensitivity for basic compounds.
Waters Corp Sep-Pak Alumina B 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 30/pk
Sep-Pak Alumina B Vac cartridges contain a highly active grade of alumina with a basic 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 basic alumina is also low-capacity ion exchanger in aqueous media. Sep-Pak Alumina B Vac cartridges can be used to extract phospholipids, steroids, and catecholamines. Since Sep-Pak Alumina B is unaffected by high-energy radioactivity, these cartridges can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Vac Cartridge, Alumina B, 100 mg, 1 cc, 50-300 μm
These Alumina B Vac cartridges feature a highly active alumina with a basic surface chemistry, providing a polar surface for analyte retention and behaving as a Lewis acid. They are designed for use with vacuum manifolds and automated solid phase extraction instruments.
- Contains highly active grade of alumina with basic surface chemistry.
