Solid Phase Extraction
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 Sep-Pak Cartridge, Alumina A, 280 mg Sorbent, 50-300 μm, Plus Light
These cartridges feature a highly active grade of alumina with an acidic surface chemistry, providing an extremely polar surface for analyte retention. They are a normal phase sorbent, suitable for radioactive compound isolation, and designed for efficient elution with minimal solvent.
- Highly active alumina with acidic surface chemistry.
- Extremely polar surface for analyte retention.
- Normal phase sorbent, comparable to silica, stable under high pH.
- Low-capacity ion exchanger in aqueous media.
- Resistant to high-energy radioactivity.
- Reduced internal diameter and distinctive finned outer body.
- Minimal elution volume, improving recoveries and reducing solvent consumption.
Waters Corp Sep-Pak Cyanopropyl (CN) 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 55 - 105 µm, 20/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
