Waters Corp Sep-Pak Cartridge, Alumina N, 280 mg, 50-300 μm
Supplier: Waters Corp WAT023561
Sep-Pak Alumina N Plus Light cartridges feature a highly active alumina sorbent with neutral surface chemistry for normal-phase solid phase extraction. This sorbent provides an extremely polar surface for analyte retention, similar to silica but more stable under high pH conditions. Its unique design minimizes interstitial volume, allowing efficient elution in minimal solvent and optimizing recoveries.
