SPE Disks and Cartridges
Waters Corp Sep-Pak Cyanopropyl (CN) 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 100/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 Diol 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 100/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 tC2 Plus Short Cartridge, 400 mg Sorbent per Cartridge, 37 - 55 µm, 50/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 Florisil 3 cc Vac RC Cartridge, 500 mg Sorbent per Cartridge, 50 - 200 µm, 50/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
Waters Corp Sep-Pak C18 Plus Short Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 2000/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.
