Waters Corp Sep-Pak Classic Cartridge, Alumina B, 1850 mg Sorbent, 50 – 300 μm
Sep-Pak Alumina B Classic cartridges utilize highly active alumina with a basic surface chemistry for analyte retention and as a low-capacity ion exchanger.
- Highly active alumina with basic surface chemistry for polar retention and Lewis acid properties.
- Normal phase sorbent, stable under high pH; also acts as a low-capacity ion exchanger.
- Extracts phospholipids, steroids, and catecholamines; unaffected by high-energy radioactivity.
- Classic-style cartridges designed for Luer-tip syringe use and vacuum-assisted flow via adaptor.
Waters Corporation Solid Phase Extraction Vac Cartridge, Oasis MCX, 3 cc, 60 mg, 60 μm
Oasis MCX 3 cc Vac Cartridge features a novel, mixed-mode polymeric sorbent for high selectivity and sensitivity in basic compound extraction. It is water wettable, ensuring consistent recoveries even if it runs dry. Designed for viscous samples (60 μm particle size), it is compatible with vacuum manifolds and automated SPE. Offers pH stability from 0 to 14 and higher binding capacity than silica-based sorbents, facilitating method development.
