SPE Disks and Cartridges
Waters Corp Sep-Pak Alumina N Plus Light Cartridge, 280 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina N Plus Light 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 have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
Waters Corp Sep-Pak Accell Plus QMA Plus Short Cartridge, 360 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Plus Short 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 versatile cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.

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 Aminopropyl (NH2) 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 100/pk
Sep-Pak Amino Propyl (NH2) Vac cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak tC18 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty. Typical applications include analyte isolation and enrichment from biological, environmental and food samples.
Waters Corp Sep-Pak Aminopropyl (NH2) Classic Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Classic cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. 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.

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 6 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 30 µm, 30/pk
The 6 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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
