SPE Disks and Cartridges
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 Sep-Pak Silica 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 100/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 Cyanopropyl (CN) Plus Light Cartridge, 130 mg Sorbent per Cartridge, 55 - 105 µm, 50/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 Aminopropyl (NH2) Plus Light Cartridge, 130 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Plus Light 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 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 Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Plus Light 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.

Waters Corp Sep-Pak tC2 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 100/pk
Silica-based bonded phase with low hydrophobicity character; use for methods requiring less retention than C8; applications are similar to C18 and C8.
Waters Corp Sep-Pak Accell Plus QMA 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 37 - 55 µm, 50/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 Florisil Plus Long Cartridge, 910 mg Sorbent per Cartridge, 50 - 200 µm, 2000/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
Waters Corp Sep-Pak tC18 1 cc Vac Cartridge, 100 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 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 DNPH-Silica Plus Short Cartridge, 350 mg Sorbent per Cartridge, 55 - 105 µm, 20/pk
Specially designed for analyzing formaldehyde, other aldehydes and ketones in air.
Waters Corp Sep-Pak C18 Vac RC Cartridge, 100 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 Sep-Pak Silica Plus Long Cartridge, 690 mg Sorbent per Cartridge, 55 - 105 µm, 2000/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 XPoSure Plus Short Cartridge, 350 mg Sorbent per Cartridge, 500-1000 µm, 20/pk
Specially designed for monitoring aldehydes in indoor air.
Waters Corp Sep-Pak tC18 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
