SPE Disks and Cartridges
Waters Corp Sep-Pak Accell Plus CM 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Sep-Pak Accell Plus CM Vac cartridges contain a silica-based, hydrophilic weak cation-exchanger with large pore size (300Å). The cartridges are designed for extraction of cationic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of molecules such as cationic proteins. Other applications include extraction of steriods, pesticides, and herbicides. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C8 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Sep-Pak Cyanopropyl (CN) 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 55 - 105 µm, 20/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
Waters Corp Sep-Pak Cyanopropyl (CN) 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 30/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
Waters Corp Sep-Pak Alumina B 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 50 - 300 µm, 20/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 Oasis HLB 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 500/pk
The 1 cc Oasis HLB cartridges contain the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent that was developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol. Since the Oasis HLB sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The product is designed for automated SPE on the Gilson ASPEC.
Waters Corp Oasis HLB 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 500/pk
The 3 cc Oasis HLB cartridges contain the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent that was developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol. Since the Oasis HLB sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The product is intended for automated SPE on the Gilson ASPEC.
