SPE Disks and Cartridges
Waters Corp Waters Sep-Pak Cartridge, Diol, 130 mg, 37 to 55 μm
This silica-based polar bonded phase cartridge has a neutral character. It can be used as an alternative to silica in normal-phase applications where the acidic character of silica is undesirable, or as a very weakly interacting phase in aqueous applications. Key applications include the isolation of antibiotics from cosmetics and the isolation of proteins or peptides by hydrophobic interaction chromatography.

Waters Corp Sep-Pak Aminopropyl (NH2) Vac RC Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Vac RC 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 feature an integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples. They can be used with robotic sample preparation equipment or with vacuum manifolds.
