Solid Phase Extraction
Waters Corp Sep-Pak Vac Cartridge, tC18, 200 mg, 37 to 55 μm
The Sep-Pak tC18 Vac Cartridge features a silica-based bonded phase with strong hydrophobicity and trifunctional bonding chemistry for increased hydrolytic stability. Designed for analyte isolation and enrichment from biological, environmental, and food samples, it also facilitates solvent switching and removal of sample components that elute after analytes of interest on liquid chromatography columns.
- Streamlines protocols and simplifies sample handling.
- Eliminates emulsion challenges.
- Reduces exposure to dangerous agents, improving safety.
- Allows direct field sampling, bypassing lab transfer.
- Packing material secured by two polyethylene frits.
- Cartridge body made of molded, high-purity polypropylene.
- Connects to multi-position vacuum manifolds via male-Luer tip.
- Constructed from inert polypropylene to prevent analyte reactions.
Waters Corp Sep-Pak Accell Plus CM 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Sep-Pak Accell Plus CM Vac cartridges contain a silica-based, hydrophilic weak cation-exchanger with large pore size (300Å). The cartridges are designed for extraction of cationic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of molecules such as cationic proteins. Other applications include extraction of steriods, pesticides, and herbicides. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
