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 Vac Cartridge, Florisil, 500 mg, 6 cc, 50–200 μm
This vac cartridge features Florisil, an extremely polar sorbent (magnesium oxide and silica gel blend) for adsorbing low to moderate polarity species. It's used for pesticide analysis in regulated food and environmental methods. Designed for sample enrichment and purification, it aids in easy extraction and transfer without spillage or evaporation loss. Product integrity is maintained by a non-contaminating poly-foil pouch.
- Highly active, weakly basic sorbent.
- Effective for pesticide analysis.
- Facilitates convenient sample transfer.
- High-quality, reproducible packings.
- 20 μm frit offers solvent resistance and good flow.
- Frit acts as a depth filter.
Waters Corp Waters Vac Cartridge, Accell Plus QMA, 6 cc, 1 g Sorbent, 37 to 55 μm
These cartridges feature a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å). Designed for extracting anionic analytes in aqueous and non-aqueous solutions, they are ideal for isolating larger molecules such as proteins and removing acidic pigments in food extracts. Syringe-barrel type, they are compatible with vacuum manifolds and automated SPE instruments.
