SPE Disks and Cartridges
Waters Corp Sep-Pak C18 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55-105 µm Particle Size, 300/pk
Silica-based octadecyl bonded phase with strong hydrophobicity; used to adsorb analytes of even weak hydrophobicity from aqueous solutions; typical applications include drugs and their metabolites in serum, plasma or urine, desalting of peptides, trace organics in environmental water samples, organic acids in beverages.
Waters Corp Oasis HLB 5 cc Glass Vac Cartridge, 200 mg Sorbent per Cartridge, 60 µm, 30/pk
The Oasis HLB glass cartridges are optimized for trace analysis at parts-per-trillion (PPT) level. Each lot is tested for the presence of bisphenol A and other phenols and phthalates, assuring that endocrine disruptors can be analyzed to PPT levels.
Waters Corp Certified Sep-Pak Silica 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55-105 µm, 30/pk
Certified Sep-Pak Silica 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55-105 µm, 30/pk
Waters Corp Oasis MCX 20 cc Vac Cartridge, 1 g Sorbent per Cartridge, 60 µm, 20/pk
The 20 cc Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX 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 60 µm particle size is recommended when working with viscous samples. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Certified Sep-Pak Alumina B 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50 - 300 µm, 30/pk
6 cc Vac Cartridge of Certified Sep-Pak Alumina B, each containing 1 g of sorbent per cartridge.
Waters Corp Certified Sep-Pak Alumina B 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
3 cc Vac Cartridge of Certified Sep-Pak Alumina B, each containing 500 mg of sorbent per cartridge.
Waters Corp Certified Sep-Pak Alumina A 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 30/pk
6 cc Vac Cartridge of Certified Sep-Pak Alumina A, each containing 500 mg of sorbent per cartridge.
Waters Corp Certified Sep-Pak Alumina N 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Certified Sep-Pak Alumina N Vac cartridges contain a highly active grade of alumina with a neutral 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 neutral alumina is suitable for applications such as synthetic crude oil fractionation. Certified Sep-Pak Alumina N cartridges are quality controlled to ensure reproducible separations. The cartridges provide superior performance for ultra-low level analyte detection by reducing the potential for background interferences found in many SPE devices. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Alumina A 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50 - 300 µm, 30/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.
Waters Corp Sep-Pak Accell Plus QMA 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Sep-Pak Accell Plus QMA Vac cartridges contain a silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å). The cartridges are designed for extraction of anionic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of larger molecules such as anionic proteins such as immunoglobulins and enzymes. Other applications include isolation of phenolic compounds and removal of acidic pigments in wine, fruit juices, and food extracts. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Cyanopropyl (CN) 20 cc Vac Cartridge, 5 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 Diol 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
Silica-based polar bonded phase with neutral character; can be used as an alternative to silica in normal-phase applications, where the acidic character of silica is undesirable or as very weakly interacting phase in aqueous applications; applications include antibiotics from cosmetics; isolation of proteins or peptides by hydrophobic interaction chromatography.
