SPE Disks and Cartridges
Waters Corp Sep-Pak tC18 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty; applications similar to C18.
Waters Corp Sep-Pak tC18 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty; applications similar to C18.
Waters Corp Sep-Pak Florisil 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 50 - 200 µm, 20/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
Waters Corp Sep-Pak Alumina N 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 50 - 300 µm, 20/pk
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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Silica 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 55 - 105 µm, 10/pk
Polar sorbent, used primarily to adsorb analytes from non polar solvents like hydrocarbons, chloro- or flouro-substituted hydrocarbons or less polar esters and ethers.
Waters Corp Sep-Pak C8 Vac RC Cartridge, 100 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 Sep-Pak Porapak RDX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 125-150 µm, 30/pk
Specially cleaned polymeric poly(divinylbenzene-vinylpyrrolidone) resin with hydrophobic character. Can be used as an alternative to octadecyl-bonded silica for preparation of analytes that weakly adsorb to silica-based reversed-phase sorbents. Compatible with sample or eluents at high and low pH. Specifically designed for the concentration of high explosives in aqueous samples.
American Chromatography Supplies LLC SPE LUER MAXI-CLEAN 600MG C18
NC2082412 SPE LUER MAXI-CLEAN 600MG C18
Agilent Technologies GLYKOCLEAN S CARTRIDGE
Cartridgeused for clean up of glycan samples after fluorescent labeling. Also in combination with GlycoClean R to purify glycans from N-glycanase digests prior to Signal 2-AA or 2-AB labeling.
Waters Corp Oasis HLB 1 cc Vac RC Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 50/pk
These Vac RC cartridges contain the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent for 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 cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of greater volumes of samples or solvents. They can be used with robotic sample preparation equipment or with vacuum manifolds.
