SPE Disks and Cartridges
Agilent Technologies Bond Elut C18 cartridge, 500 mg, 3 mL, 120 μm, 50 per Pack
The most hydrophobic, bonded silica sorbent in the Bond Elut range. Regarded as having the broadest spectrum of retention among bonded silica sorbents. Extremely retentive for nonpolar compounds.
Waters Corp Oasis WCX 1 cc Vac Cartridge, 10 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc Oasis WCX cartridges contain the Oasis WCX sorbent, which is a polymeric reversed-phase, weak ion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong basic compounds and quaternary amines. Since the Oasis WCX 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 Sep-Pak tC18 1 cc Vac Cartridge, 50 mg Sorbent per Cartridge, 37 - 55 µm, 100/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty; applications similar to C18.
Waters Corp Oasis MCX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
The 3 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 Alumina A Plus Long Cartridge, 1710 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina A Plus Long 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 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.
Waters Corp Sep-Pak C8 Plus Short Cartridge, 400 mg Sorbent per Cartridge, 37 - 55 µm, 50/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 Certified Sep-Pak Alumina A 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
3 cc Vac Cartridge of Certified Sep-Pak Alumina A, each containing 500 mg of sorbent per cartridge.
Biotage Pacific Premium Oil & Grease Disk, 90 mm
Pacific Premium disks, available in both 47 mm and 90 mm, offer excellent recovery and precision. Pacific Premium Oil and Grease SPE Disks provide fast flow rates with dirty samples while offering high recovery values for the oil and grease fraction of the sample. These disks blend various diameters of high quality borosilicate glass micro-fibers; the upper surface of each disk provides a greater porosity, essential for handling particulate heavy samples, and the bottom layer, comprised of smaller micro-fibers and packing material, retains the oil and grease fraction.
