Waters Corp Sep-Pak Aminopropyl (NH2) 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 500/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 C18 Plus Long Cartridge, 820 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 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 55 - 105 µm, 20/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.
