Waters Corp Sep-Pak Accell Plus QMA Carbonate Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Carbonate Plus Light cartridges contain a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. These cartridges are used for extraction of anionic analytes in aqueous and non-aqueous solutions when the chloride counter-ion in the standard Sep-Pak Accell Plus QMA cartridges interferes with the analysis. These Light-style 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) Classic Cartridge, 360 mg, 55 to 105 μm
These Sep-Pak Aminopropyl (NH2) Classic cartridges provide a moderately polar, silica-based bonded phase with a weakly basic surface. They function as polar sorbents or weak anion exchangers (below pH 8), ideal for extracting various analytes including phenols, saccharides, drugs, and metabolites.
- Moderately polar, silica-based bonded phase with a weakly basic surface
- Functions as a polar sorbent or weak anion exchanger (below pH 8)
- Suitable for extracting phenols, phenolic pigments, petroleum fractionation, saccharides, drugs, and metabolites
- Designed for positive displacement with Luer-tip syringes
- Attachable to vacuum-assisted flow devices with a male/male adaptor
Waters Corp Waters Sep-Pak C18 Vac Cartridge, 20 cc, 5 g Sorbent, 55–105 μm
This silica-based bonded phase cartridge features strong hydrophobicity and is designed to adsorb analytes of even weak hydrophobicity from aqueous solutions. It behaves similarly to reversed-phase HPLC columns and is suitable for various applications, including the analysis of drugs and their metabolites in serum, plasma, or urine, desalting of peptides, trace organics in environmental water samples, and organic acids in beverages. The state-of-the-art packing process and precision design make it suitable for robotic applications and convenient for manual use.
