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. 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 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.
