SPE Disks and Cartridges
Waters Corp Sep-Pak C8 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 37 - 55 µm, 10/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) 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 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 Diol 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 37 - 55 µm, 20/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 Oasis PRiME MCX 6 cc Vac Cartridge, 150 mg Sorbent per Cartridge, 30 µm, 30/pk
Oasis PRiME MCX 6 cc Vac Cartridge, 150 mg Sorbent per Cartridge, 30 µm, 30/pk
Waters Corp Oasis PRiME HLB 6 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 30/pk;
Oasis PRiME HLB 6 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 30/pk;
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 Sep-Pak C18 Plus Short Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 50/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 Oasis MCX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 30 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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C18 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 55 - 105 µm, 10/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.
