SPE Disks and Cartridges
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 Oasis MAX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 60 µm, 100/pk
The 3 cc Oasis MAX cartridges contain the Oasis MAX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting acidic compounds with anion-exchange groups. Since the Oasis MAX 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 Sep-Pak C18 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 55 - 105 µm, 20/pk
Silica-based 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; similar in behavior to reversed-phase HPLC columns.
Waters Corp Sep-Pak Accell Plus CM Classic Cartridge, 360 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Classic 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 Classic-style cartridges are designed for use with positive displacement by a Luer-tip syringe and can also attach easily to vacuum-assisted flow devices using a male/male adaptor.
Waters Corp Sep-Pak Alumina N 3 cc Vac RC Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina N Vac RC 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. These cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples. They can be used with robotic sample preparation equipment or with vacuum manifolds.
Waters Corp Sep-Pak Cyanopropyl (CN) 3 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 55 - 105 µm, 50/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 Silica 3 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
A polar stationary phase, used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons or less polar esters and ethers. Analyte retention can occur through hydrogen bonding, dipole-dipole interactions or in aqueous samples through cation-exchange.
Biotage ATLANTIC HLB DISK-M 30PK
Atlantic HLB Medium Capacity SPE Disk is designed for samples with medium organic content and extracting EPA 8270,8081,8082 (semi-volatile organic compounds) and EPA 1694 ( Pharmaceutical By-Products). This is a great in.all purpose in. disk which provides excellent extraction of a large range of semi-volatile compounds.
Waters Corp Sep-Pak Aminopropyl (NH2) 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55-105 µm Particle Size, 300/pk
Silica-based polar bonded phase with basic character; can be used as a polar sorbent, like silica, with different selectivity for acidic/basic analytes or as weak anion exchanger in aqueous medium; applications include phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites.
Waters Corp Sep-Pak Cyanopropyl (CN) 1 cc Vac Cartridge, 50 mg Sorbent per Cartridge, 55 - 105 µm, 100/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.
