Waters Corp Waters Corporation Solid Phase Extraction Cartridge, Alumina A, 1850 mg, 50–300 μm
Supplier: Waters Corp WAT051800
Sep-Pak Alumina A Classic cartridges feature a highly active grade of alumina with an acidic surface chemistry, providing an extremely polar surface for analyte retention and acting as a Lewis acid. This normal phase sorbent is comparable to silica in use but offers greater stability under high pH conditions. It also functions as a low-capacity ion exchanger in aqueous media and is unaffected by high-energy radioactivity, making it suitable for isolating radioactive compounds. These Classic-style cartridges are designed for positive displacement with a Luer-tip syringe and can be easily attached to vacuum-assisted flow devices using a male/male adaptor.
- Highly active alumina with acidic surface chemistry.
