SPE Disks and Cartridges
Waters Corp Sep-Pak Silica 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 30/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.
Waters Corp Sep-Pak Silica 3 cc Vac Cartridge, 500 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.
Waters Corp Oasis HLB 3 cc Vac Cartridge, 540 mg Sorbent per Cartridge, 60 µm, 100/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 60 µm particle size is recommended when working with viscous samples.
Waters Corp Sep-Pak Diol Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/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.
Waters Corp Certified Sep-Pak Alumina N 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50 - 300 µm, 30/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 Oasis WAX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc Oasis WAX cartridges contain the Oasis WAX sorbent, which is a polymeric reversed-phase, weak anion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong acidic compounds. Since the Oasis WAX 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.
Waters Corp Oasis MCX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 60 µm, 100/pk
The 1 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 MCX 1 cc Flangeless Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless 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 flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp Oasis MAX 1 cc Flangeless Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless 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 flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
